ABB 1SBN040200R1013 WA4-96-13 mechanical latching unit for AF contactors and NF contactor relays with 100–250 V AC/DC impulse control.
£36.62
The ABB 1SBN040200R1013 is a reliable mechanical latching unit designed for ABB AF contactors and NF contactor relays where maintained operation is required during loss of coil supply voltage. As part of the ABB WA4 mechanical latching accessory series, it provides a dependable solution for creating electrically maintained contactor systems in industrial control applications.
This latching accessory allows compatible ABB contactors to remain mechanically held in the energised position even when the contactor coil supply is interrupted. The WA4 design incorporates mechanical locking with electromagnetic impulse unlatching or manual release, improving system reliability in applications where contactor status must be maintained.
With a 100–250 V AC/DC control range and compatibility with ABB AF09 to AF96 contactors, the ABB 1SBN040200R1013 is ideal for industrial switching systems, motor control panels and automation installations requiring secure mechanical contactor retention.
Mechanical latching units are used in applications where contactors must remain closed without continuous coil energisation. By mechanically holding the contactor position, they provide additional reliability for industrial systems affected by temporary power interruptions or control supply failures.
The ABB WA4-96-13 provides a compact and practical method of converting compatible ABB contactors into mechanically latched contactors. Its front-mounted design allows integration into existing control panels while maintaining ABB contactor system flexibility.

The ABB 1SBN040200R1013 is a mechanical latching unit used to keep compatible ABB contactors switched on even if the coil supply voltage is removed or fails.
The WA4-96-13 mechanical latch is designed for ABB AF09 to AF96 contactors and NF contactor relays.
The unit operates with a 100–250 V AC/DC impulse control range.
The contactor can be released electrically using an impulse signal or manually using the release button on the front of the latching unit.
The ABB WA4-96-13 is clipped onto the front face of a compatible ABB contactor inside industrial control panels and electrical systems.
ABB WA4 mechanical latching units are widely used in industrial automation and electrical control systems to provide reliable contactor retention, improved operational continuity and flexible switching solutions.
