    Ground fault monitor for grounded and high-resistance grounded AC systems

    The RCM475LY monitors for ground fault current in grounded and high-resistance grounded AC systems, both single-phase and three-phase. The RCM475LY features a steplessly adjustable setpoint from either 6 mA...600 mA or 10 mA...10 A. Display features include power and alarm LEDS, as well as an LED bar graph indicating how close the system is to the alarm value. An adjustable time delay of 0...10 s is available.

    The device may be set to latching or non-latching operation, and features one DPDT alarm relay which may be set to normally energized or normally de-energized operation. The RCM475LY includes a built-in current transformer.
