Square D 9422 RP-1 Circuit Breaker Operating Mechanism

The Square D 9422RP1 Operating Mechanism is a flange-mounted, variable-depth operating device rated for 600 VAC and 250 A, NEMA, designed to drive Square D PowerPact KAL/KHL 2-3 pole circuit breakers in industrial panels. It can be mounted on either the right- or left-hand flange and supports variable mounting depth, enabling secure integration in custom enclosures and, when paired with 9422 handle mechanisms (A9/A10), remote operation. Schneider Electric discontinued 9422RP1 on August 22, 2023, with end-of-service dated September 15, 2023, and directs customers toward a broader family of 9422-class variable-depth mechanisms. The recommended replacement range notes compatibility with PowerPact frame families including H, J, D, M, and P, providing flexible upgrade paths for retrofits or new installations where a 9422-style mechanism is required.
