WA4-10 24VDC Mechanical Latching Unit

WA4-10 mechanical latching units for AF09(Z) ... AF38(Z) contactors and NF(Z) contactor relays ensures 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.
