1SBN040200R1014

ABB 1SBN040200R1014 – WA4-96-14 is a mechanical latching unit designed for compatible ABB AF80 and AF96 contactors. The accessory converts a standard electrically operated contactor into a mechanically maintained switching device, enabling the contactor to remain in its operated or closed position even after the normal contactor-coil supply has been removed. The WA4-96-14 version is designed for a broad 250–500 V AC at 50/60 Hz and 250–500 V DC control-voltage range.
