CURRENT RELAYS (current on/off) for current recognition In OR-circuits recognize when there is a AC-current in 1 of up to 12 monitored lines and switch on for instance a central suction system. Current relays in AND-circuits only switch on when there is a AC-current in all 3 monitored lines and report for instance a break of a phase.
