IEfficient energy management and continuity of service with source-changeover systemTo ensure continuity of service for critical applications, LV electrical installations need to be connected to at least two independent power sources:

* The replacement source (R) can be: a second power source (with possibly different characteristics from the normal source) or an electrical generator

1 A normal source (N)

2And a replacement

source (R)*used to supply energy to the installation when the normal source unavailable, or, for instance, when its quality and/or availability is no longer guaranteed.

The source-changeover

system switches the load (partly or fully) between these two sources.

A few basics on source-changeover systems> A source-changeover system can be automated to manage transfers according to external conditions.

> Switching from a main power source to a replacement source can be performed either manually or automatically.

> A source-changeover system comprises circuit breakers, switch-disconnectors or contactors.

to switch the load to meet your needs

Automatic source-changeover system(or ATSE: Automatic Transfer Switching Equipment)

An automatic controller may be added to a remote-operated source-changeover system. It is possible to automatically control source transfer according to programmed (dedicated controllers) or programmable (PLC) operating modes. These solutions ensure optimum energy management.

3

ApplicationsCommercial and service sector (operating rooms in hospitals, safety systems for buildings, computer rooms for banks and insurance companies, lighting and emergency lighting systems in malls, etc.), industry and infrastructure.

System2 or 3 circuit breakers that may have different configurations, linked by an electrical interlocking system. A mechanical interlocking system protects against electrical malfunctions or incorrect manual operations, with an automatic control system (dedicated controllers or PLC).

1 Manual source-changeover system (or MTSE: Manual Transfer Switching Equipment)The simplest way to switch the load. It is controlled manually by an operator. The time required to switch from the N source to R source can vary.

ApplicationsBuildings and infrastructure where the need for continuity of service is significant but not a priority: offices, small and medium-sized businesses.

System2 or 3 mechanically interlocked manually-operated circuit breakers or 2 switch-disconnectors.

3ways

Remote-operated source-changeover system(or RTSE: Remote Transfer Switching Equipment)

The most commonly used system for devices with high ratings. No direct human intervention is required. Source-changeover is controlled electrically.

System2 or 3 circuit breakers that may have different configurations, linked by an electrical interlocking system. In addition, a mechanical interlocking system protects against electrical malfunctions or incorrect manual operations.

ApplicationsIndustry (assembly lines, engine rooms on ships, critical auxiliaries in thermal powerstations, etc.); Infrastructure (port and railway installations, runway lighting systems, control systems on military sites, etc.).

IV

A source-changeover system is indispensable for applications that need a continuous supply of electric power (hospitals, airports, banks, government facilities, etc.). But a source-changeover system is also suitable for all LV electrical installations exposed to:> Nominal voltage loss or dip (when there is high demand for electric power)> Unpredictable power quality> Frequent power cuts.

For critical applications in particularFor all others in general

These factors, and many others, can damage the continuity of service of your electrical installation.For infrastructure managers, a source-changeover system gives direct economic benefi ts: it is possible to select your source based on power cost. In this case, the replacement source (R) is used as an alternative, more economical source.

s All Compact and Masterpact circuit breakers and Compact switch-disconnectors from 100 to 6300 A with rotary handles or motor mechanisms can be interlocked.

Interlocking is based on two identical keylocks with a single key and a keylock adapter (different for each device). This solution enables interlocking between two devices that are physically distant or that have very different characteristics, for example between a low and a medium-voltage device, or between Compact NSX circuit breakers and switch-disconnectors.A system of wall-mounted captive key boxes makes possible a large number of combinations between many devices.

Mechanical interlocking of two or three devices is used to create a remote-operated source-changeover system. A basic mechanical interlocking system enhances the reliability of system operation.

Interlocking of two Compact NSX100 to 630 devices using a base plateA base plate designed for two Compact circuit breakers can be installed horizontally or vertically on a mounting rail. Interlocking is carried out on the base plate by a mechanism located behind the breakers. Access to the circuit breaker controls and trip units is conserved. Circuit breakers must be fixed or plug-in versions, with or without earth-leakage protection or measurement modules. The base plate and the circuit breakers are supplied separately.

b Base plate for Compact NSX100 to 250 devicesThis base plate is intended for two Compact NSX100 to 250 devices.

b Base plate for Compact NSX400 to 630 devicesThis base plate is intended for two Compact NSX400 to 630 devices. It may also be used, without any modifications, to interlock a fixed Compact NSX100 to 250 with a Compact NSX400 or 630 device.An adapter kit is required for plug-in versions of the Compact NSX100 to 250 devices.Compact NSX100 to 250 devices, in both fixed and plug-in versions, may be equipped with spreaders.

Electrical interlocking is used with a mechanical interlocking system. An automatic controller may be added to take into account information from the distribution system.

Morover, the relays controlling the closing order to the Normal and Replacement circuit-breakers must be mechanically and/or electrically interlocked to prevent them from giving simultaneous closing commands.

Electrical interlocking is carried out by an electrical control device.For Compact NSX up to 630 A, electrical interlocking is implemented by the IVE unit integrating control circuits and an external terminal block in accordance with the pages C-5 to C-4 of the chapter Electric diagrams of this catalogue. The integrated control circuits implement the time delays required for correct source transfer.For Compact NS630b to 1600 and Masterpact, this function can be implemented in one of two ways:

b using the IVE unit b by an electrician based on the diagrams in accordance with the pages C-9 to C-14

of the chapter Electric diagrams of this catalogue.

Characteristics of the IVE unit b External connection terminal block: v inputs: circuit breaker control signals v outputs: status of the SDE contacts on the Normal and Replacement source

circuit breakers. b 2 connectors for the two Normal and Replacement source circuit breakers: v inputs:

- status of the OF contacts on each circuit breaker (ON or OFF) - status of the SDE contacts on the Normal and Replacement source circuit breakers

v outputs: power supply for operating mechanisms. b Control voltage: v 24 to 250 V DC v 48 to 415 V 50/60 Hz - 440 V 60 Hz.

The IVE unit control voltage must be same as that of the circuit breaker operating mechanisms.

The BA controller is used to create simple source-changeover systems that switch from one source to another depending on the presence of voltage UN on the Normal source.It is generally used to manage two permanent sources and can control Compact NS, Compact NSX and Masterpact NT/NW circuit breakers and switch-disconnectors.

Operating modesA four-position switch may be used to select:

b automatic operation b forced operation on the Normal source b forced operation on the Replacement source b stop (both Normal and Replacement sources off).

Setting the time delaysTime delays are set on the front of the controller.t1. delay between detection that the Normal source has failed and the transmission of the order to open the Normal source circuit breaker (adjustable from 0.1 to 30 seconds).t2. delay between detection that the Normal source has returned and the transmission of the order to open the Replacement source circuit breaker (adjustable from 0.1 to 240 seconds).

Circuit breaker commands and status indicationsThe status of the circuit breakers is indicated on the front of the controller.

b ON, OFF, fault.A built-in terminal block may be used to connect the following input/output signals:

b inputs: v voluntary order to transfer to source R (e.g. for special tariffs, etc.) v additional control contact (not part of the controller). Transfer to the Replacement

source takes place only if the contact is closed (e.g. used to test the frequency of UR, etc.)

b outputs: v indication of operation in automatic or stop mode via changeover contacts.

TestIt is possible to test the operation of the BA controller by turning OFF (opening) the P25M circuit breaker for the Normal source and thus simulating a failure of voltage UN.

The UA controller is used to create a source-changeover system integrating the following automatic functions:b transfer from one source to another depending on the presence of voltage UN on the Normal sourceb startup of an engine generator setb shedding and reconnection of non-priority circuitsb transfer to the Replacement source if one of the phases on the Normal source fails.The UA controller can control Compact NS, Compact NSX and Masterpact NT/NW devices.

Operating modesA four-position switch may be used to select:

b automatic operation b forced operation on the Normal source b forced operation on the Replacement source b stop (both Normal and Replacement sources off, then manual operation).

Setting the time delaysTime delays are set on the front of the controller.t1. delay between detection that the Normal source has failed and the transmission of the order to open the Normal source circuit breaker (adjustable from 0.1 to 30 seconds).t2. delay between detection that the Normal source has returned and the transmission of the order to open the Replacement source circuit breaker (adjustable from 0.1 to 240 seconds).t3. delay following opening of QN with load shedding and before closing of QR (adjustable from 0.5 to 30 seconds).t4. delay following opening of QR with load reconnection and before closing of QN (adjustable from 0.5 to 30 seconds).t5. delay for confirmation that UN is present before shutting down the engine generator set (adjustable from 60 to 600 seconds).t6. delay before startup of the engine generator set (120 or 180 seconds).

Commands and indicationsCircuit breaker status indications on the front of the controller:

b ON, OFF, fault.A built-in terminal block may be used to connect the following input/output signals:

b inputs: v voluntary order to transfer to source R (e.g. for special tariffs, etc.) v additional control contact (not part of the controller). Transfer to the Replacement

source takes place only if the contact is closed (e.g. used to test the frequency of UR, etc.)

b outputs: v control of an engine generator set (ON / OFF) v shedding of non-priority circuits v indication of operation in automatic mode via changeover contacts.

Distribution-system settingsThree switches are used to:

b select the type of Normal source, whether single-phase or three-phase (e.g. 240 V single-phase or 240 V three-phase)

b select whether to remain (or not) on the Normal source if the Replacement source is not operational during operation on special tariffs

b select the maximum permissible startup time for the engine generator set during operation on special tariffs (120 or 180 seconds).

TestA pushbutton on the front of the controller may be used to test transfer from the Normal source to the Replacement source, then the return to the Normal source. The test lasts approximately three minutes.

COM communications optionUsing the internal bus protocol, this option may be used to remote the following information:

b circuit breaker status (ON, OFF, fault trip) b presence of the Normal and Replacement voltages b presence of an order for forced operation (e.g. special tariffs) b settings and configuration information b status of non-priority circuits (loads shed or not)

b position of the switch (stop, auto, forced operation on the Normal source, forced operation on the Replacement source).
