Power Distribution System - Module 17plus

Supplier: E-T-A

Module 17plus is a power distribution system for use with E-T-A circuit breakers type 2210-S... or 3600-.../3900-... or electronic circuit breaker ESS20 or SSRPC E-1048-7.


Each module accommodates two single pole plug-in circuit breakers with an individual housing width of only 12.5 mm and fits onto all industry standard mounting rails.

The two-way modules can be interconnected to provide as many ways as required with a terminal block fitted at each end for connection of signalling circuits.

A distribution busbar can be fitted on the supply side of the modules though each pole of multipole circuit breakers must be individually connected. Electrical connections are by means of screwless spring loaded terminals.

Circuit breakers featuring make and break auxiliary contacts should be specified when either single or group signalisation is required. For group signalisation, the make contacts (which open in the event of a fault) are connected in series to the terminal blocks of the modules.

The module is designed to accommodate a probe for series connection continuity tests. When multipole circuit breakers are fitted auxiliary contacts are required for each pole. Individual circuit breaker signalisation is achieved through use of the break contacts (which close in the event of failure) connected in parallel by means of terminals on each module.

Both types of signalisation (individual and group signalisation) are available at the same time if the circuit breakers used provide auxiliary contacts (please note when ordering).

The signalling circuitry between modules is automatically connected when modules are linked together.
