Power Distribution System SV2 Description The ETA power distribution system SV2 is designed to accommodate the electronic circuit breaker series ESS20003 or electronic circuit protector ESX0. It distributes the current supplied by a switch mode power supply up to 40 A to 4, 8, 2 or channels. Input connections are via screw terminals. The individual circuit breakers can be plugged in. Loads are connected via springloaded screwless terminals. The power distribution includes integral wiring of the signalisation of the individual channels which can be combined to a group signal. The SV2 can be snapped onto a DIN symmetrical rail.
