Square D 9421LHP48 Circuit Breaker Handle 9421LW7

Product Description

The SQUARE D 9421LHP48 is a replacement operating mechanism handle designed for use with circuit breaker operating mechanisms in electrical distribution systems. This handle serves as the physical interface for manually operating the mechanism, allowing qualified electricians to engage or disengage breakers during maintenance, testing, or emergency shutoff procedures. Measuring 8.8 inches in length, 6.8 inches in width, and 4.5 inches in height, it provides a robust, properly sized grip point for the mechanism assembly. Installation is straightforward for electrical professionals familiar with enclosed breaker gear.

This handle is intended for use specifically with the 9421LW7 operating mechanism. Typical applications include industrial and commercial electrical panels, switchgear enclosures, and distribution equipment where an external handle mechanism is required for breaker operation without direct panel access. It is suited for retrofit and replacement scenarios where the original handle has worn or been damaged.
