The ABB 1SVR750660R0200 is a CM-IWN.1S insulation monitoring relay. It continuously measures the insulation resistance of an ungrounded (IT) power system and signals when the resistance drops below a set threshold, preventing undetected ground faults from escalating into phase-to-phase faults or equipment damage.
Package and handling
Supplied in a retail package, which is the standard individual box for a panel component. No special handling required beyond normal ESD precautions for electronic relays.
