Square D 9421L PowerPacT Rotary Handle Mechanism, NEMA 1/3R/12

The Square D 9421L PowerPacT rotary handle mechanism is a Type L door-mounted operating accessory engineered for PowerPacT M, P, and R-Frame circuit breakers rated A to 1200A. Built with heavy-duty, all-metal construction and a long shaft configuration, this field-installable handle mounts directly to the enclosure door and carries a NEMA 1/3R/12 rating for both indoor and outdoor installations. Associated motor-protection applications on this platform span Motor FLA ratings from 125A to 800A, with the shared rotary handle, NEMA enclosure rating, and heavy-duty metal construction remaining constant across that range. The kit ships complete with a support bracket and all hardware required to mount the handle to the enclosure flange, giving panel builders and contractors a straightforward retrofit or new-build solution.
