Protector Trip Relay
KRM161B/C monitors resultant insulation level between a non-grounded single or three phase AC mains and its protective earth. It can monitor both live or non-live network.
The trip level is factory set and relay will operate after a delay of approximately two seconds. Relay is fail-safe and energises when powered. Link terminal 6 and 10 to make a non-latching relay.
Only ONE KRM16x can be connected to each IT-system.
KRM161B/C unit uses a superimposed DC monitoring voltage and so only one unit can be connected to each isolated system.
