E-T-A Circuit Breakers Ltd

The power distribution system SVS20 for rail mounting distributes the current supplied by a DC 24 V switch-mode power supply to 8 channels and selectively protects the connected loads by means of the inserted circuit breakers. With a max. load current of 8 A per channel and a max. total current of 40 A the SVS20 provides ease of wiring in short-circuit limited DC 24 V applications. Eight protected "L+" load outputs per channel and 35 minus terminals help to reduce wiring time significantly.

Modular distribution rail, each module accommodating 2 magnetic or hydraulic-magnetic circuit breakers type 8340-F and associated load terminals. Circuit breaker status indication (group signalisation) is via 2 busbars. Power supply is via right- or left-side terminal block. Live parts in the plug-in and supply feed terminal areas are protected against brush contact. Circuit breakers may be replaced with power on.

Distribution rail for one module suitable for ETSI control cabinet and similar applications. One module comprises 4 positions for magnetic or hydraulic-magnetic circuit breakers type 8340-F and associated line and load terminals. Circuit breaker status indication (group signalisation) is via two busbars. The modular design facilitates the operation of a single distribution rail at two different voltages.

Live parts in the plug-in and supply feed terminal areas are protected against brush contact.

Expansion or circuit breaker replacement is possible with power on.

Distribution rail with modules connected in series. One module provides 4 positions for magnetic or magnetic-hydraulic circuit breakers type 8340-F and the pertinent line and load terminals on the front and rear side of the rail. Supply feed is either on the right or left side with copper busbars. Trip indication of the circuit breakers (group signalisation) is possible via two signal busbars. Live parts in the plug-in area of the load terminals are protected against brush contact. Circuit breaker replacement is possible with power on.

Distribution rail comprising series connected circuit breaker mounting modules. Each module accommodates one magnetic or magnetic-hydraulic circuit breaker type 8345 and the associated line and load terminals on the rear side of the rail. Supply feed is either on the right or left side with copper busbars. Trip indication of the circuit breakers (group signalisation) is possible via two signal busbars.

Live parts in the plug-in area of the load terminals are protected against brush contact (IP20). Replacement of circuit breakers (switched off) is possible with power on.

The electronic circuit breaker type ESS22-T extends the E-T-A product range of electronic circuit protection for DC 24 V applications. It is a double pole version providing physical isolation. It meets the requirements of the machinery directive 2006/42/EC and the affiliated standard EN 60204-1 "Safety of Machinery, Electrical Equipment of Machines", para 9.4.3.1.

The combination of active electronic current limitation in the event of a short circuit and overload disconnection from 1.1 times rated current provides double pole selective protection of DC 24 V load systems.

DC 24 V power supplies, which are widely used in industry today, will shut down the output in the event of an overload with the result that one faulty load in the system can lead to complete disconnection of all loads. As well as an unidentified failure this also means stoppage of the whole system.
