Using EasyPact SPS Closing the circuit breaker

Closing conditionsClosing (i.e. turning the circuit ON) is possible only if the circuit breaker is "ready to close". The prerequisites are the following:

b device open (OFF) b springs charged b no opening order present.

The circuit breaker will not close unless it is "ready to close" when the order is given.

Closing the circuit breakerLocally (mechanical)Press the mechanical ON pushbutton.

Remotely

Anti-pumping functionThe purpose of the mechanical anti-pumping function is to ensure that a circuit breaker receiving simultaneous opening and closing orders does not open and close indefinitely. If there is a continuous closing order, after opening the circuit breaker remains open until the closing order is discontinued. A new closing order is required to close the circuit breaker. A new order is not required if the closing release is wired in series with the PF "ready to close" contact.

When connected to a remote control panel, the XF closing release can be used to close the circuit breaker remotely.

Overview of functionsCurrent protecton


Protection settingsDepending on the type of installation, it is possible to set the tripping curve of yourMicroprocessor based ET Trip System using the parameters presented below.

Thermal memoryThe thermal memory continuously accounts for the amount of heat in the cables,both before and after tripping, whatever the value of the current (presence of anoverload or not). The thermal memory optimises the long-time protection functionof the circuit breaker by taking into account the temperature rise in the cables.The thermal memory assumes a cable cooling time of approximately 20 minutes.

Protection of the fourth pole on four-pole circuit breakers (Refer page 29)Type of neutral Description.

Ground-fault protection on ET6G Trip System A ground fault in the protection conductors can provoke local temperature riseat the site of the fault or in the conductors.The purpose of the ground-fault protection function is to eliminate this type of fault.Type Description

1. ground-fault and neutral protection are independent and can therefore becombined.

Neutral protection for three-pole devicesNeutral protection is not available on three-pole devices.

6G

Residual 1. the function determines the zero-phase sequencecurrent, i.e. the vectorial sum of the phase and neutralcurrents2. it detects faults downstream of the circuit breaker.

Neutral protection The cross-sectional area of the neutral conductor is equalat In to that of the phase conductors.

1. the long-time current setting Ir for the neutral is equalto the setting value

2. the short-time pick-up Isd for the neutral is equal tothe setting value

3. the instantaneous pick-ups Isd and Ii for the neutralare equal to the setting value.

2. ground-fault protection in 3P+N system is activated by installing a external sensor(CT) in the neutral conductor and connecting to Microprocessor based ET Trip System.

Technical appendix Thermal memory

Thermal memoryThe thermal memory is a means to simulate temperature rise and cooling causedby changes in the flow of current in the conductors.

These changes may be caused by:1. repetitive motor starting;2. loads fluctuating near the protection settings;3. repeated circuit-breaker closing on a fault.Microprocessor based ET Trip System without a thermal memory (contrary to bimetal strip thermalprotection) do not react to the above types of overloads because they do notlast long enough to cause tripping.However, each overload produces a temperature rise and the cumulative effectcan lead to dangerous overheating.

Microprocessor based ET Trip System with a thermal memory record the temperature rise causedby each overload. Even very short overloads produce a temperature risethat is stored in the memory.This information stored in the thermal memory reduces the tripping time.

Microprocessor based ET Trip System and thermal memoryAll Microprocessor based ET Trip System are equipped as standard with a thermal memory.

1. for all protection functions, prior to tripping, the temperature-rise and cooling timeconstants are equal and depend on the tripping delay in question:a. if the tripping delay is short, the time constant is low;b. if the tripping delay is long, the time constant is high.

2. for long-time protection, following tripping, the cooling curve is simulatedby the Microprocessor based ET Trip System.Closing of the circuit breaker prior to the end of the timeconstant (approximately 20 minutes) reduces the tripping time indicatedin the tripping curves.

Short-time protection and intermittent faultsFor the short-time protection function, intermittent currents that do no provoketripping are stored in the Microprocessor based ET Trip ystem memory.This information is equivalent to the long-time thermal memory and reducesthe tripping delay for the short-time protection.Following a trip, the short-time tsd tripping delay is reduced to the value ofthe minimum setting for 20 seconds.

Ground-fault protection and intermittent faultsThe ground-fault protection implements the same function as the short-timeprotection.

Inspecting and testing before use

Initial testsProcedure

A general check of the circuit breaker takes only a few minutes and avoids any risk of mistakes due to errors or negligence.A general check must be carried out:

b prior to initial use b following an extended period during which the circuit breaker is not used.

A check must be carried out with the entire switchboard de-energised. In switchboards with compartments, only those compartments that may be accessed by the operators must be de-energised.

Electrical testsInsulation and dielectric-withstand tests must be carried out immediately after delivery of the switchboard. These tests are precisely defined by international standards and must be directed and carried out by a qualified expert.

Prior to running the tests, it is absolutely necessary to: b disconnect all the electrical auxiliaries of the circuit breaker (MCH, MX, XF, MN) b remove the long-time rating plug on the 2.0, 6G control units.

Switchboard inspectionCheck that the circuit breakers are installed in a clean environment, free of any installation scrap or items (tools, electrical wires, broken parts or shreds, metal objects, etc.).

Conformity with the installation diagramCheck that the devices conform with the installation diagram:

b breaking capacities indicated on the rating plates b identification of the control unit (type, rating) b presence of any optional functions (remote ON/OFF with motor mechanism,

auxiliaries, measurement and indication modules, etc.) b protection settings (long time, short time, instantaneous, earth fault) b identification of the protected circuit marked on the front of each circuit breaker.

Condition of connections and auxiliariesCheck device mounting in the switchboard and the tightness of power connections.Check that all auxiliaries and accessories are correctly installed:

b electrical auxiliaries b terminal blocks b connections of auxiliary circuits.

OperationCheck the mechanical operation of the circuit breakers:

b opening of contacts b closing of contacts.

Check on the control unitIdentify the control unit of each circuit breaker Please refer page no. 22

These operations must be carried out in particular before using a EasyPact device for the first time.


49HRB75971 - 03/2013HRB75971 - 03/2013

Note the faultFaults are signalled locally and remotely by the indicators and auxiliary contacts installed on circuit breakers (depending on each configuration). See page 11 in this manual and the user manual of the control unit for information on the fault indications available with your circuit breaker.

Identify the cause of trippingA circuit must never be reclosed (locally or remotely) before the cause of the fault has been identified and cleared.A fault may have a number of causes:

b depending on the type of control unit, fault diagnostics are available. See the user manual for the control unit.

b depending on the type of fault and the criticality of the loads, a number of precautionary measures must be taken, in particular the insulation and dielectric tests on a part of or the entire installation. These checks and test must be directed and carried out by qualified personnel.

Inspect the circuit breaker following a short-circuit b Check the arc chutes (see page 51) b Check the contacts (see page 51) b Check the tightness of connections (see the device installation manual) b Check the disconnecting-contact clusters (see page 51).

Reset the circuit breakerThe circuit breaker can be reset locally or remotely. See page 11 in this manual for information on how the circuit breaker can be reset.
