Schneider Electric 9421LH6 Door Mounting Handle

Schneider Electric Square D 9421LH6 is a 6-inch, black door-mounting rotary operating handle kit for PowerPact and Compact NSF circuit breakers. Designed to mount to the enclosure door flange, it provides front-door manual operation of the breaker and interlocks with the door to help ensure isolation when the handle is in the Off position. The assembly supports 2- or 3-pole configurations on PowerPact B/H/J/L breakers with a 125 A frame size, and is listed as the door-mounted option for these families in Schneider Electric catalogs. The 9421LH6 is a Type 1, 3R, 12 handle, intended for use in standard enclosure environments (NEMA 1/3R/12). The kit is padlock-capable, allowing up to three padlocks to secure the handle and keep the door closed during isolation. The package includes all parts needed to mount the handle to the enclosure flange according to Schneider Electric mounting dimensions, making it a straightforward replacement for existing LH-type door mechanisms on compatible PowerPact installations.
