Block Contactors

The WA4 mechanical latching unit for AF09 ... AF96 contactors and NF contactor relays ensures that the contactor or contactor relay remains switched on even if there is a lack or a failure of voltage. 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...
