KRM161-DC - INSULATION RELAY FOR INACTIVE NON-LIVE DC SYSTEMS
- Insulation "megger" for non grounded non-live DC circuits
- 0-110VDC system voltage
- "IDV" measuring principle
- For use in land, marine and offshore for alarm-lamps, Lantern, DC motors etc.
KRM161-DC monitors resultant insulation level between a non-grounded non-live DC network and its protective earth.
The trip level is preset at factory and relay will operate when insulation is below trip level after a delay of 2-5 seconds. Relay is fail-safe and energises when powered. Link terminal 15 and 16 to make a non-latching relay.
KRM161-DC unit injects a DC voltage signal into the monitored network and measure the earth leakage flow to the ground.
Only ONE unit can be connected to each isolated system.
Terminal 1 and 2 must be disconnected when network is powered.
