Circuit Breaker Locking Bracket

Maintaining consistent mechanical tripping performance relies on the dimensional stability of this small, high-precision latch component used within low-voltage circuit breaker operating mechanisms. Its irregular profile features a vertical mounting base, a horizontal actuation arm, and specific cutouts that interface with the electromagnetic trip unit to translate magnetic force into rapid contact separation.

Manufactured via precision progressive die stamping, the part requires strict control over springback and bending angles to ensure the latch releases reliably under fault conditions without jamming. Critical tolerances focus on the relative position between the pivot point and the engagement tip, as well as the flatness of the mounting surface, which are verified using optical coordinate measuring machines to prevent assembly interference in compact switchgear layouts.

The facility supports full-process manufacturing from mold design to mass production, utilizing high-speed precision presses for consistent batch output. Surface treatments such as electro-galvanizing or nickel plating are available to enhance corrosion resistance and electrical insulation properties. Pricing and lead times are determined by annual volume, material specification (typically carbon steel or alloy steel), and the complexity of required secondary operations like deburring or heat treatment.
