Why Choose the ABB ZAF1650-70 Operating Coil?
The ABB ZAF1650-70 is a genuine replacement operating coil set designed for compatible ABB AF series block contactors. Supplied as a set of two coils, it provides the electromagnetic operating components required when servicing high-current AF contactors in industrial controlgear installations.
The ZAF1650-70 operates across a wide 100–250 V AC at 50/60 Hz and 100–250 V DC rated control circuit voltage range. This wide-range AC/DC capability provides flexibility across industrial control supplies while maintaining the electrical characteristics required by the compatible contactor platform.
Designed for ABB AF1350, AF1650 and AF2050 contactors, the ZAF1650-70 uses screw terminals for secure control-circuit connections. The coil set measures approximately 180 × 90 × 130 mm and has a net weight of approximately 0.9 kg, providing an application-specific ABB service solution for maintenance and refurbishment.

- Screw-terminal connections.
- Original ABB contactor service component.
- Designed for maintenance, repair and controlgear refurbishment.
The operating coils generate the magnetic force required to actuate the contactor when the specified control voltage is applied. The ABB ZAF1650-70 provides the two-coil set required by compatible AF1350, AF1650 and AF2050 contactors, making it an important service component for these high-current contactor platforms.
With a 100–250 V AC/DC control range, the ZAF1650-70 accommodates a broad range of industrial control supplies. Replacing the operating coils can support refurbishment of the contactor's control mechanism while allowing other serviceable contactor components to remain in use where appropriate.
