Abstract:

As the market’s dual demands for performance and cost of molded case circuit breakers(MCCBs) continue to rise, structural innovation has become crucial. An innovative structure of MCCB that eliminates the traction rod and directly adopts a design featuring a backup armature and an adjustment screw for tripping and reclosing is introduced. The principle and structural characteristics of this design are elaborated, and its advantages in reducing costs and improving performance are analyzed through a comparison with the traditional traction rod structure. Practical experience has demonstrated that this innovative design effectively meets the market’s demand for high performance and low cost of MCCBs, and has broad application prospects.

Key words: molded case circuit breaker, removal of traction rod, multi-stage transmission, cost reduction, performance improvement
