SIGNALING BLOCK

3 Poles

n Differential fault indication and visual display of breaker operating states:

-(1) + (2) tripping due to short circuit.

-(2) tripping due to overload and general trip condition.

-(3) overload early warning signal in the event that the long time response setting is about to be exceeded (i.e. useful for load shedding purposes).

n Each function signals via a pair of contacts (1 N.O. and 1 N.C.).

n Mounts directly onto lower portion of circuit breaker

n Required supply voltage: 24-230 V, AC or DC.

n Field Installable
