Ground Fault Relay

EL3100 Series – Ground Fault Relay

The Littlefuse EL3100 series Ground Fault Relay operates on ungrounded ac systems. It is a self-powered unit used to detect ground faults for three-phase systems. The EL3100 meets the NEC Article 250.21(B) and the CEC requirements for ground detectors for ungrounded alternating-current systems. Voltage connections are provided for 208, 240, 480, and 600 V systems. The EL3100 can operate stand-alone or with up to five remote LED indicators. A solid-state relay output provides indication of a ground fault. The output relay is closed when the 3-phase neutral voltage shifts as the result of ground leakage. Three green LEDs indicate the presence of phase-to-ground voltage, and one red LED indicates a ground fault.
