Output Table — CurrentWatch EGF Series

Normally Energized Models

Protection from faults and control power loss.

Normally De-energized Models

Protection from faults only when power is applied.

Latching (Mechanical Relay Output) Models

Latching models power up initially in the rest (normal) mode. If there is a fault

condition or the test button is pushed, the output contacts will change state

and latch. The output will remain latched regardless of whether the fault is

cleared or control power is removed. To reset the output, apply a momentary

contact across “reset” terminals.
