The ABB WA4-13 af09-af65 nf 100-250v mech latching is a versatile mechanical latching unit designed for AF09(Z) to AF65, and AFC09 to 38 contactors, as well as NF(C)(Z) contactor relays. This unit ensures that the contactor or relay remains engaged even during voltage failures, making it ideal for energy conservation applications. It allows for easy conversion of standard contactors into compact latched contactors. The WA4 block features a mechanical latching device with options for electromagnetic impulse unlatching (AC or DC) or manual unlatching.
With a wide range of control voltages available (100 to 250 V 50/60 Hz - DC), the WA4 coil can be selected quickly to suit your needs. Enhance your auxiliary control circuit by adding 1-pole front mounted CA4 and 2-pole side mounted CAL4 auxiliary contact blocks. The design is optimized for easy installation, requiring 25% less depth in panel mounting. Additionally, this solution reduces stock requirements and offers a broader range of solutions with 50% fewer variants compared to conventional options.
