Power Distribution System SVS02
Description
The E-T-A power distribution system SVS02 is designed to accommodate
the electronic circuit breaker series ESS20-003 or electronic circuit
protector ESX10. It distributes the current supplied by a switch mode
power supply up to 40 A to 4, 8, 12 or 16 channels. Input connections
are via screw terminals. The individual circuit breakers can be plugged
in. Loads are connected via spring-loaded screwless terminals. The
power distribution includes integral wiring of the signalisation of the
individual channels which can be combined to a group signal. The
SVS02 can be snapped onto a DIN symmetrical rail.

Power Distribution System SVS02
Application example for jumper to replace
The signalling pathway of the group signalisation is as follows:
- feed-in of +DC 24 V potential in (SC = terminal 31.2)
- via in-built overcurrent protection CB1
- via all signal contacts of the fitted circuit breakers type ESS20-003
- back to signal output of group signalisation (S0 = terminal 31.3)
In operating condition (i.e. all circuit breakers plugged in and
functional) the signalling pathway (SC) to (S0) is closed.
If the distribution rail is not completely fitted with ESS20-003,
the open pathway (SC) to (S0) may be closed by means of a
jumper type SB-S11-P1-01-1-1A
