Littelfuse's EL3100 Ground Fault Indication System protects operators from shock hazards

Littelfuse's EL3100 Ground Fault Indication System indicates the presence of ground faults on ungrounded three-phase electrical systems while protecting operators from shock hazards.

The EL3100 phase- and ground-fault-indication device enables users to monitor the system voltage both locally and remotely. It features contact output for alarm communication with a SCADA system or PLC. In addition, its LED indication module does not bring the system voltage to the door of the enclosure and is waterproof, providing safety to operators even in wet and outdoor applications.

The UL Listed EL3100 indication system helps customers meet the National Electric Code (NEC) or Canadian Electrical Code (CEC) requirements that call for ground fault detectors on ungrounded systems. The EL3100 system, which is mounted in the back of the cabinet, has onboard LEDs. An optional remote indication module may be mounted at the panel door. The LEDs come in two configurations: a single LED that indicates a ground fault and a plate-mounted four-LED panel that indicates a ground fault and voltage status of each phase. A contact output can be used to send an alarm signal. The system is powered directly from the three-phase input lines and requires no external power source.
