Can the ELM earth leakage module be used for ground fault alarm (without tripping)?
Issue:
Ground fault alarm with ELM
Product Line:
Circuit Breakers
Resolution:
No, the ELM cannot be used as an alarm only device. Doing so will damage the ELM.
If the alarm only function is required, consider the Square D® Vigirex® ground fault relays.
NOTE: The companion circuit breaker must have an S29392 48 Vdc shunt trip accessory installed.
If shunt trip S29392 is not installed in the circuit breaker, it must be installed before placing into service.
