1SBN040200R1012

ABB 1SBN040200R1012 – WA4-96-12 is a front-mounted mechanical latching unit designed specifically for ABB AF80 and AF96 contactors. It converts a standard electrically operated contactor into a mechanically latched contactor, allowing the contactor to remain securely in its closed position even after the operating coil supply voltage has been removed or lost. The WA4-96-12 operates over a wide control-voltage range of 48–130 V AC at 50/60 Hz and 48–130 V DC. This makes one accessory suitable for several commonly used control voltages within the specified range.
