Masterpact NW


2/993

The original Masterpact has

set a new standard for power

circuit breakers around the

world. Over the years, other

major manufacturers havetried to keep up by developing

products incorporating

Masterpacts most innovative

features, including the

breaking principle, modular

design and the use of

composite materials.

Today, Schneider Electric continues to

innovate with the new Merlin Gerin

Masterpact NW.

In addition to the traditional features of

power circuit breakers (withdrawability,

discrimination and low maintenance),

Masterpact now offers built-in

communications and metering

functions, all in optimised frame sizes.

Masterpact NW incorporates the latest

technology to enhance both

performance and safety. Easy to install,

with user-friendly, intuitive operation

and environment-friendly design, it is,

quite simply, the ultimate ACB.

Things

Four performance levels

H1 - for industrial sites with high short-circuit levels or installations with

two parallel-connected transformers.

H2 - high-performance for heavy industry where very high short-circuits

can occur.

H3 - for incoming devices supplying critical applications requiring both

high performance and a high level of discrimination.

L1 - for high current-limiting capability and discrimination levels, as yet,

unequalled by any other circuit breaker of its type. Intended for theprotection of cable-type feeders or to raise the performance level of a

switchboard when the transformer power rating is increased.

Integration in a communications

network

Masterpact can be integrated in a general supervision system to optimiseinstallation operation and maintenance. The communication architecture

is open, and may be upgraded for interfacing with any protocol.

Switch-disconnector versions

The switch-disconnectors are derived directly from the circuit breakersand offer the same features and performance levels.

New Masterpact,new levels of performance

1000 V and 400 Hzdistribution systemsThe Masterpact rangecan be used on 1000V

installations (miningindustry) and 400Hz

systems (aeronautics,computer centres).

Practical installationsolutions

The new range improves upon all the

installation solutions which have already made

Masterpact a success. It has been designed to

standardise switchboards, optimise volumes

and simplify installation:

Incoming connection to top or bottom

terminals.

No safety clearance required.

Connection: Horizontal or vertical rear connection.

Front connection with minimum extra space.

Mixed front and rear connections.

115 mm pole pitch on all versions.

No derating up to 55C and 4000A.

Optimised volumes

Up to 4000A, Masterpact NW circuit breakers

are all the same size, the same size as the

previous M32 frame.

From 4000A to 6300A, there is just one size,

which is considerably smaller than before.

Retrofit solutions

Special connections are available to replace a

fixed or drawout Masterpact M08 to M32 with a

Masterpact NW, without modifying the busbars

Optimisedvolumes


6/997

With optimised sizes, the Masterpact NW rangesimplifies the design of switchboards and selection/

installation of devices:

Three connection layouts for Masterpact NW:

One from 800 to 3200A (NW08 - NW32).

One for 4000 A (NW40a).

One 4000 to 6300A (NW40b - NW63).

Identical auxiliary connection terminals from 800

to 6300A (Masterpact NW).

Front connections do not impact on the depthof the device.

Rear connections are converted from

vertical or horizontal busbars, simply by

turning the connectors through 90.

Vertical front connection of a fixed Masterpact NW.Vertical and horizontal rear connection

of a fixed Masterpact NW.

Ease ofinstallation

Connection to busbars.


7/998

Greater dependabilityFiltered breaking

The patented new design of the arc chutes includes stainless-steel filters.

The chutes absorb the energy released during breaking, thus limiting the

stresses exerted on the installation. They filter and cool the gases

produced, reducing the external effects of short circuit clearance.

Automatic unlatching(H3 and L1)The automatic unlatching of the circuit breaker operating mechanism for

high short-circuits extends performance up to 150kA. It produces ultra-

fast tripping for all short-circuits higher than 37 kA (L1) and 65 kA (H3).For lower short-circuits, the system does not react so that the control unit

can provide total discrimination with downstream devices.

More intelligent trip units

Today, with the high speed of calculation, the small size of memory and

advances in miniaturisation, trip units have become circuit breaker control

units offering increasingly powerful functions. They accurately measure

system parameters, instantly calculate values, store data, log events,

signal alarms, communicate, take action, etc. The new Masterpact range

equipped with Micrologic control units, constitute both an extremely

reliable protective device and an accurate measurement instrument.

User friendly

Intuitive use

Micrologic control units are equipped with a digital LCD display used in

conjunction with simple navigation buttons. Users can directly access

parameters and settings. Navigation between screens is intuitive and the

immediate display of values greatly simplifies settings. Text is displayed in

the desired language.

backed by incomparable securityProtection functions are separate from the measurement functions and

are managed by an ASIC electronic component. This independence

guarantees immunity from conducted or radiated disturbances and

ensures a high degree of reliability.

A patented double setting system for protection functions establishes:

A maximum threshold set using the control-unit dials.

Fine adjustments via the keypad or remotely.

The fine adjustments for thresholds (to within one ampere) and tripping

delays (to within a fraction of a second) are displayed directly on the

screen.

The control unit cover can be lead-sealed to prevent uncontrolled access

to the dials and protect the settings.

control unit.

Ready forthe future

Compliance withenvironmentalrequirements

Schneider Electric fully take into account

environmental requirements, starting right from

the design phase of every product, through to

the end of its service life:

The materials used for Masterpact are not

dangerous to the environment.

The production facilities are non-polluting in

compliance with the ISO 14001 standard.

Filtered breaking eliminates pollution in the

switchboard.

The energy dissipated per pole is low,

making energy losses insignificant.

The materials are marked to facilitate sorting

for recycling at the end of product service

life.

Simple upgrading of

installationsInstallations changes and power level increases

normally mean new equipment and

switchboards extensions:

All control units are interchangeable.

Communication with a supervision system is

an option that may be added at any time.

A reserve chassis can be pre-addressed so

that system parameters do not have to be

modified when a drawout device is installed

at a later date.

Micrologic control unitsOverview of functions

All Masterpact circuit breakers can beequipped with a Micrologic control unit.

Control units are designed to protect Powercircuits and loads. Alarms may beprogrammed for remote indications.Measurements of current, voltage,frequency, power and power qualityoptimise continuity of service and energymanagement.

Dependability

The use of an ASIC electronic component for protection functions in all Micrologiccontrol units, guarantees a high degree of reliability and immunity to conducted orradiated disturbances.

On Micrologic A, P and H* control units, advanced functions are managed by anindependent microprocessor.

Control unitsMicrologic P power

Micrologic P control units include all thefunctions offered by Micrologic A.

In addition, they measure voltages andcalculate power and energy values.They also offer new protection functionsbased on current, voltages, frequency andpower based load protection.

Protection settings........................................................ +The adjustable protection functions are identical to those of Micrologic A(overloads, short-circuits, earth-fault and earth-leakage protection).

Double settingWithin the range determined by the adjustment dial, fine adjustment of thresholds(to within one ampere) and time delays (to within one second) is possible with thekeypad or remotely via the COM option.

IDMTL settingCoordination with fuse-type or medium-voltage protection systems is optimised byadjusting the slope of the overload-protection curve.

Neutral protectionOn three-pole circuit breakers, neutral protection may be set using the keypad orremotely using the COM option, to one of four positions: neutral unprotected (4P3t), neutral protection at 0.5 In (4P 3t + N/2), neutral protection at In (4P 4t) andneutral protection at 2 In (4P 3t + 2N). Neutral protection at 2 In is used when theneutral conductor is twice the size of the phase conductors (major load imbalance,high level of third order harmonics).

On four-pole circuit breakers, neutral protection may be set using a three-positionswitch or the keypad: neutral unprotected (4P 3t), neutral protection at 0.5 In (4P 3t+ N/2), neutral protection at In (4P 4t). IDMTL protection settings offer three phaseprotection only.

Programmable alarms and other protection ......................

Depending on the set thresholds and time delays, the Micrologic P control unitmonitors currents and voltage, power, frequency and the phase sequence. Eachthreshold overrun is signalled remotely via the COM option and may be combinedwith tripping (protection) or an indication carried out by an optional M2C or M6Cprogrammable contact (alarm), or both (protection and alarm).

Load shedding and reconnection........................................Load shedding and reconnection parameters may be set according to the power orthe current flowing through the circuit breaker. Load shedding is carried out by a

supervisor via the COM option or by an M2C or M6C programmable contact.

Measurements .......................................................................

The Micrologic P control unit calculates (in real time) all the electrical values (V, A,W, VAR, VA, Wh, VARh, VAh, Hz), power factors and crest factors.The Micrologic P control unit also calculates demand current and demand powerover an adjustable time period.In the event of tripping on a fault, the interrupted current is stored. The optionalexternal power supply makes it possible to display the value with the circuit breakeropen.

Histories and maintenance indicators ................................

The last ten trips and alarms are recorded in two separate history files.Maintenance indications (contact wear, operation cycles, etc.) are recorded forlocal access.

Indication option via programmable contacts

The M2C (two contacts) and M6C (six contacts) auxiliary contacts may be used tosignal threshold overruns or status changes. They can be programmed using thekeypad on the Micrologic P control unit or remotely using the COM option.

Communication option (COM)The communication option may be used to:cRemotely read and set parameters for the protection functions.cTransmit all the calculated indicators and measurements.cSignal the causes of tripping and alarms.cConsult the history files and the maintenance-indicator register.An event log and a maintenance register, stored in control-unit memory but notavailable locally, may be accessed in addition via the COM option.

Protection functionsAll current-based protection functions require no auxiliary source. Voltage-basedprotection functions are connected to AC power via a voltage measurement input builtinto the circuit breaker.

Measurement functionsMeasurement functions are independent of the protection functions.The high-accuracy measurement module operates independently of the protectionmodule, while remaining synchronised with protection events.

Measurement-calculation modec Measurement functions are based on the new zero blind time concept which

continuously measures signals at a high sampling rate, rather than the traditionalblind window process. This method ensures accurate energy calculations even forhighly variable loads (welding machines, robots, etc.).

c Energies are calculated on the basis of the instantaneous power values, in two ways:v The traditional mode where only positive (consumed) energies are consideredv The signed mode where the positive (consumed) and negative (supplied) energies

are considered separately.

Accuracy of measurements (including sensors)c Voltage (V) 1%.c Current (A) 1.5%.cFrequency (Hz) 0.1 Hz.c Power (W) and energy (Wh) 2.5%.

Stored informationThe fine setting adjustments, the last 100 events and the maintenance register remain inthe control-unit memory even when power is lost.

Time-stampingTime-stamping is activated only if an external power supply module is present (max. driftof 1 hour per year).

Communicationbus

COMmodule

CommunicationCommunication architecture

The (COM) communication option isrequired for integration of the circuit

breaker or switch-disconnector in asupervision system.Masterpact uses Modbus or Jbuscommunications protocol for fullcompatibility with SMS PowerLogic(electrical network) management systems.An external gateway is available forcommunication over ethernet networks.

COM communication option

For fixed devices, the COM option comprises of a communication module installedwithin the device and supplied by a set of sensors (OF, SDE ,PF and CH micro-contacts) kit for connection to XF and MX communicating voltage releases.

For drawout devices, the COM option comprises of:c A communication module within in the device and supplied by a set of

auxilliaries (OF, SDE, PF and CH micro-contacts) and/or a kit for connection toXF and MX communicating voltage releases.

c A communication module installed on the chassis and supplied by a set ofsensors (CE, CD and CT contacts).

Each installed device has an address that is assigned via the keypad of the controlunit (Modbus) or remotely (Batibus). The address of a drawout device is assignedto the chassis which maintains the same address if the device is replaced.

Status indication by the COM option is independent of the auxiliary indicationcontacts. These contacts remain available for conventional uses.

Device communication moduleThis module is independent of the control unit. Installed in the device, behind the

control unit, it receives and transmits information on the communication network.An infra-red link transmits data between the control unit and the communicationmodule.Consumption: 100 mA.

Chassis communication moduleInstalled on the chassis, this module makes it possible to address the chassis andto maintain the address when the circuit breaker is in the disconnected position.Consumption: 100 mA.

CommunicationMasterpact in a communicationnetwork

Functionsand characteristics

DevicesCircuit breakers equipped with Micrologic control units may be connected to either

a Digipact or Modbus communication bus. The information made availabledepends on the type of Micrologic control unit (A, P or H) and on the type ofcommunication bus (Digipact or Modbus).Switch-disconnectors may be connected exclusively to the Digipact communicationbus.

Communication bus

Digipact bus

The Digipact bus is the internal bus of the low-voltage switchboard in which theDigipact communicating devices are installed (Masterpact with Digipact COM,PM150, SC150, UA150, etc.). This bus must be equipped with a DC150 dataconcentrator (see the Powerlogic System catalogue).

AddressesAddressing is carried out by the DC150 data concentrator.

Number of devicesThe maximum number of devices that may be connected to the Digipact bus iscalculated in terms of communication points. These points correspond to theamount of traffic the bus can handle. The total number of points for the variousdevices connected to a single bus must not exceed 100.If the required devices represent more than 100 points, add a second Digipactinternal bus.

Communicating device Number of points

DC150 data concentrator 4

Micrologic + Digipact COM 4

PM150 4

SC150 4

UA150 4

Length of busThe maximum recommended length for the Digipact internal bus is 200 meters.

Bus power sourcePower is supplied by the DC150 data concentrator (24 V)..


30/9931

Modbus busThe Modbus RS485 (JBus) system is an open bus on which communicatingModbus devices (Masterpact with Modbus COM, PM300, Sepam, Vigilohm, etc.)

are installed. All types of PLCs and microcomputers may be connected to the bus.

AddressesThe software layer of the Modbus protocol can manage up to 255 addresses (1 to 255).The device communication module comprises three addresses linked to:ncircuit-breaker manager;nmeasurement manager;nprotection manager.The chassis communication module comprises one address linked to:nthe chassis manager.The division of the system into four managers secures data exchange with thesupervision system and the circuit-breaker actuators.The manager addresses are automatically derived from the circuit-breaker address@xx entered via the Micrologic control unit (the default address is 47).

logic addresses@xx Circuit-breaker manager (1 to 47)

@xx + 50 Chassis manager (51 to 97)

@xx + 200 Measurement managers (201 to 247)

@xx + 100 Protection manager (101 to 147)

Number of devicesThe maximum number of devices that may be connected to the Modbus busdepends on the type of device (Masterpact with Modbus COM, PM300, Sepam,Vigilohm, etc.), the baud rate (19200 is recommended), the volume of dataexchanged and the desired response time. The RS485 physical layer offers up to32 connection points on the bus (1 master, 31 slaves).A fixed device requires only one connection point (communication module on thedevice).A drawout device uses two connection points (communication modules on thedevice and on the chassis).The number must never exceed 31 fixed devices or 15 drawout devices.

Length of busThe maximum recommended length for the Modbus bus is 1200 meters.

Bus power sourceA 24 V DC power supply is required (less than 20% ripple, insulation class II).

Communication interfaceThe Modbus bus may be connected to the central processing device in any ofthree manners:ndirect link to a PLC. The communication interface is not required if the PLC isequipped with a Modbus port;ndirect link to a computer. The Modbus (RS485) / Serial port (RS232)communication interface is required;nconnection to a TCP/IP (Ethernet) network. The Modbus (RS485) / TCP/IP(Ethernet) communication interface is required.

SoftwareTo make use of the information provided by the communicating devices, softwarewith a Modbus driver must be used.

Micrologic utilitiesThis is a set of Modbus drivers that may be used with a PC to:ndisplay the variables (I, U, P, E, etc.) with the RDU (Remote Display Utility)nread/write the settings with the RSU (Remote Setting Utility)nremotely control (ON / OFF) the device with the RCU (Remote Control Utility).These utilities are available upon request.

SMS (System Manager Software)SMS is a software to monitor LV and/or MV electrical energy.The SMS family includes a software range depending on the application and

function, from single product monitoring to the management of a multiple building:c Power Meter and Circuit Monitor unitsc LV devicesc Sepam units.

Two solutions are available for remoteoperation of Masterpact devices:

cA Hard wired solution.cA bus solution with the COMcommunication option.

Note:An opening order always takes priority over a closingorder.If opening and closing orders occur simultaneously(whenin the open position), the mechanism discharges withoutany movement of the main contacts. The circuit breakerremains in the open position (OFF).In the event of maintained opening and closing orders,the standard mechanism provides an anti-pumpingfunction by maintaining the main contacts in the open

position.After tripping or opening using the manual or electricalcontrols, the closing coil must first be reset before re-

closing can take place.When the automatic reset after fault trip (RAR) option isinstalled, it is impotant to ensure that the automatic/remote closing system is designed to prevent Auto-reclosing under fault trip conditions.

Electrical closing pushbutton (BPFE)

Located on the front panel, this pushbutton carries out electrical closing of thecircuit breaker.

Electrical closing via the BPFE pushbutton takes into account all the safetyfunctions that are part of the control/monitoring system of the installation.

The BPFE connects to the closing release (XF) in place of the COM module.

Remote reset after fault tripElectrical reset after fault trip (RES)

Following tripping, this function resets the fault trip indication contacts (SDE) and

the mechanical indicator and enables circuit breaker closing.Power supply: 110 / 130 V AC and 200 / 240 V AC

Automatic reset after fault trip (RAR)Following tripping, a reset of the mechanical indicator (reset button) is no longerrequired to enable circuit-breaker closing. The mechanical (reset button) andelectrical (SDE) indications remain in fault position until the reset button is pressed.
