WA4-10 is a mechanical latching unit for AF(C)09...38(Z) contactors and NF(C)(Z) contactor relays ensuring that the contactor or contactor relay remains switched on even if there is a lack or a failure of voltage, in application such as energy conservation. Standard contactors can be easily converted into compact latched contactors. The WA4 block contains a mechanical latching device with 24 V DC electromagnetic impulse unlatching or manual unlatching. • Extend your 24 V DC control solutions with a direct PLC control by 24V DC 500 mA without additional interface relay • Extend your auxiliary control circuit by adding additional 1-pole front mounted CA4 and 2-pole side mounted CAL4 auxiliary contact blocks • Design easily your installation with 25% less depth required in panel mounting.
