ABB AF-1 Contactor Relay, 4 A, 4 NC, 4 NO

The ABB contactor relay is used for switching auxiliary and control circuits including overlapping of lagging / leading contacts. It include an electronic coil interface accepting a wide control voltage Uc min. to Uc max. It has only four coils cover control voltages between 24 to 500 V 50/60 Hz or 20 to 500 V DC. It can manage large control voltage variations.

One coil can be used for different control voltages
It has built-in surge protection and do not require additional surge suppressors
8-pole contactor relays
