The SRM6 series busbar type molded case circuit breakers represent advanced protection technology for electrical distribution systems. These circuit breakers feature innovative design elements that enhance safety and performance in various industrial applications.

SRM6 Circuit Breaker

Key advantages of our busbar type circuit breakers include comprehensive protection against electric shock through fully enclosed busbar shells. This design prevents accidental contact with live parts and eliminates potential earth faults caused by environmental factors like dust or moisture. The phase-closed structure effectively prevents alternate short circuits.

Circuit Breaker Internal Structure

The integrated busbar connection design significantly reduces internal temperature rise in switchgear cabinets. By minimizing transition connection points, this structure achieves approximately 20% lower temperatures compared to conventional designs, leading to improved system reliability and longevity.

Standardized installation features include optimized 45mm busbar frame spacing, which reduces material requirements by 30% and installation volume by 20% while improving installation efficiency by 60%. Our advanced arc extinguishing system incorporates multiple structural improvements to achieve zero arcing distance operation.
