EL3100-00

Protection Relays & Controls Ground-Fault Protection – Grounded/Ungrounded AC Systems EL3100 SERIES Ground-Fault & Phase-Voltage Indicator Description The EL3100 is a self-powered ground-fault and phasevoltage indication system for 3-phase systems. The EL3100 meets the National Electrical Code (NEC) and the Canadian Electrical Code (CEC) requirements for ground detectors for ungrounded alternating-current systems. Voltage connections are provided on the EL3100 for 208, 240, 480, and 600-V systems. Three green LED’s on the EL3100 indicate the presence of phase-to-ground voltage and one red LED indicates a ground fault. 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.
