The ABB WA4-11 AF09-AF65 NF 24-60V Mechanical Latching unit is designed to enhance the functionality of standard contactors and contactor relays by ensuring they remain switched on even during voltage failures, making it ideal for energy conservation applications. This versatile unit can be easily integrated into existing systems, converting 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, providing flexibility in control. With a wide range of control voltages available (24 to 60 V 50/60 Hz - DC), the WA4 coil selection is quick and adaptable to various needs. Additionally, the unit allows for the extension of auxiliary control circuits by adding 1-pole front mounted CA4 and 2-pole side mounted CAL4 auxiliary contact blocks. Its design requires 25% less depth for panel mounting, optimizing space and reducing stock requirements by 50% compared to conventional solutions.
