Opis
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 manual unlatching.
Operation
After closing, the contactor continues to be held in the closed position by the latching
mechanism should the supply voltage fail at the contactor coil terminals.
Contactor opening can be controlled:
• electrically by an impulse (AC or DC) on the WA4 block coil (the coil is not designed to be
permanently energized)
• manually by pressing the pushbutton on the front face of the WA4 block.
Mounting
The WA4 block is clipped onto the front face of the 1-stack contactor where it takes up two
slots in central position (see fig. below).
The two other slots may accept CA4 single pole auxiliary contacts (1 block on each side of
the mechanical latch).
Additional CAL4 can be fitted on the side of the contactor in respect to the total number of
built-in or additional N.O. and N.C. auxiliary contacts as described in the accessory fitting
details part of each contactor type.

WA4 Mechanical Latching Unit is front-mounted on AF09 … AF65 contactors
and NF contactor relay. It ensures that they remain switched on, even if there is
a lack or a failure of voltage. After closing, the contactor continues to be held in
the closed position by the latching mechanism, should the supply voltage at the
contactor coil terminals fail. Contactor opening can be controlled electrically by
an impulse (AC or DC) on the WA4 block coil, or manually by pressing the
pushbutton on the front face of the WA4 block. Speed up your project by
selecting quickly the WA4 coil thanks to a wide range of control voltages from
24 to 500 V 50/60 Hz – DC (WA4-11, 12, 13, 14). And also by extending your 24
V DC control solutions with a direct PLC control by 24V DC 500 mA (WA4-10).
Optimum interface: 25% less compact than other market solutions, interface
relay already included for direct control by PLC 24 V DC 500 mA, let enough
space on AF to fix front or side-mounted auxiliary contacts in addition. Optimize
your logistic by reducing your stock and increasing your solution proposal:
standard contactors can be easily converted into compact latched contactors.
