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. Suitable for Ordering information Technical data Type SVS02 Power distribution system for ESS20-003 ● short circuit current limited DC 24 V applications ● max. 40 A continuous load ● two integral circuit breakers (CB1 and CB2): overcurrent protection of group signalisation of power distribution system, red LED glashes upon trip of CB1 ● 2 insulated wire bridges Y 303 881 08 included ● without jumpers SB-S11-P1-01-1-1A (for unused positions) Version, max. number of circuit breakers ESS20-003 on the power distribution system 04 4 channels (F1...F4) 08 8 channels (F1...F8) 12 12 channels (F1...F12) 16 16 channels (F1...F16) Screw terminals for power supply DC 24 V P310 3 loop-through terminals (X 21) max. 10 mm2 for DC 24 V (+) / DC 24 V (-) / FE functional earth Load outputs per channel (F1 ..

Power Distribution System SVS02 Application example for jumper to replace Application example for insulated wire bridge 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) Terminal X31 (group signalisation) wire bridge from (+) to (SC) internal +DC24V feed for signalisation Thus plus potential of terminal X21+ is connected to (SC) In operating condition...
