Overview

The ABB WA4-10 is a mechanical latching unit designed for use with ABB AF09 to AF38 contactors and NF contactor relays. This unit ensures the switched-on state is maintained even during voltage failures or interruptions, providing a failsafe mechanism for critical applications. It features a robust mechanical latching system. Operation includes electrical unlatching via a brief impulse to the 24 VDC coil (500 mA PLC control) or manual unlatching via the integrated pushbutton. Engineered for 2-pole + ground (2P+G) configurations, it operates at a 24 VDC control circuit voltage. The WA4 block clips directly onto the front of compatible 1-stack contactors, occupying two central slots. Auxiliary CA4 single-pole contacts can be added to either side of the mechanical latch. SKU: WA4-10. Manufacturer: ABB - Electrification. Country of Origin: DE. Compatible with ABB contactors AF09-AF38.
