Auxiliary Supply

Neutral

These terminals are the mains input connections for control supply transformer and contactor relay supply L

Main contactor coil

V AC

This terminal is internally connected to the auxiliary supply neutral and provides a convenient connection point for

the contactor coil neutral connection

Main contactor coil

V AC

This terminal is the switched output from the contactor control relay and is derived from the auxiliary supply. The

output is internally fused at 3A hence contactor coils having a high pick-up current must be operated via a slave

relay.

Note: The contacts of the Contactor Control Relay are suppressed by a series connected resistor (680 Ohms) and

capacitor (22nF) to protect the relay contacts. Users should be aware that when the contactor Control Relay is

“De-energised”, a leakage current of approximately 2mA can be expected and this should be considered when

interfacing to these terminals. Typically, there could be the energisation of very sensitive relays.
