(OLD TYPE)

KRM161x - Isolated AC Insulation Trip RelayKRM161x

  • Insulation relay for non grounded systems

  • 0-660V Line Voltage. Up to 1400V with HV adapter

  • Non isolated analogue output (C-version)

  • "IDV" measuring principle


Description
KRM161B or KRM161C 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 or KRM161C unit uses a superimposed DC monitoring voltage and so only one unit can be connected to each isolated system.
