Ground fault monitor for grounded AC systems

The RCM470LY monitors for ground fault leakage current in grounded & high-resistance grounded single & three-phase AC systems and pulsed DC type systems (Type A). Features include adjustable setpoint from either 6mA...600mA or 10mA…10A, LED meter display (0-100%), adjustable time delay from 0...10sec, fault storage, 1 DPDT alarm relay which can be set for normally energized and normally de-energized operation. An external BENDER current transformer is required for operation.

  Also required: Current transformer from the W0...W5 series. Datasheet
  Use our CT Selector to find the correct and optimal CT for your system.
