SVS20 Datasheet, PDF (1/8 Pages) ETAL Group – Systematic integration of protection and distribution functions

Power Distribution System SVS20
Description
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.
Suitable for the following circuit breaker types:
Electronic circuit breaker
ESS20-003..
Electronic circuit protector
ESX10-103..
