WA4-13

WA4-13 is a mechanical latching unit for AF09(Z) ... AF65, AFC09...38 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 electromagnetic impulse unlatching (AC or DC) or manual unlatching. Select quickly the WA4 coil thanks to an unlimited choice of control voltages (e.g. 100, 110, 115, 120, 125, 127, 208, 220, 230, 240 V 50/60 Hz - DC) included inside a large range of voltages from 100 to 250 V 50/60 Hz - DC. • 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.
