ABB WA4-96-13 Mechanical connection Piece 1 pc(s)

The mechanical linking WA4 for contactors of type AF09 ... AF96 and NF type auxiliary contactors ensure that the contactor or auxiliary contactor remains switched on even in the event of a voltage shortage or failure.
Standard contactors can easily be converted into compact linked contactors.
The Block WA4 includes mechanical declination by electromagnetic pulse (AC or DC pulse) or by hand.
The link-up keeps the closed contactor closed after it is closed if the supply voltage at the terminals of the contactor coil fails.
The contactor is opened:
– Electrically by means of a pulse (AC or DC pulse) on the coil of block WA4 (the coil is not designed for continuous control)
– Manually pressing the button on the front of the WA4 block.
The Block WA4 is snapped onto the front of the 1-level contactor and occupies two slots in the center position.
Additional auxiliary contacts can be placed on the side of the contactor.
