ABB 24-60V 50/60HZ DC MECHANICAL LATCHING UNIT WA4-11

WA4-11 is a mechanical latching unit for AF09(Z) ... AF65 contactors and NF(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 electromagnetic impulse unlatching (AC or DC) or manual unlatching. 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. Reduce your stock and increase your solution proposal with 50% of less variants required compared to conventional solutions.
