The insulation monitor IL 5881 of the series VARIMETER IMD monitors the insulation resistance of non-earthed DC systems (IT-systems) with nominal voltage up to DC 12 … 280 V. The supply voltage (auxiliary voltage) is taken from the monitored system. The device has LEDs to indicate the operating status. The response value can be set in a user-friendly way on the front of the device via a potentiometer.

Features

With reference to IEC/EN 61557-8 (see also section “Notes”)
Adjustable tripping value RAL of 5 … 200 kΩ or 10 … 500 kΩ
Selective ground fault indication for L+ and L- allows fast fault finding
Without auxiliary supply
De-energized on trip
2 changeover contacts
