CDM1-125L/4300 80A Molded Case Circuit Breaker Product Introduction
The CDM1-125L/4300 80A molded case circuit breaker is a low-voltage protection device specifically designed for power distribution systems, suitable for AC 50Hz networks with rated operational voltage up to 400V. Featuring a modular structural design and intelligent trip mechanism, this product effectively provides overload and short-circuit protection for electrical circuits, ensuring reliable safeguarding of power equipment operations.
Constructed with high-strength engineering plastic housing, the device demonstrates excellent insulation properties and impact resistance. The integrated silver alloy contact system minimizes contact resistance while enhancing electrical conductivity stability. The optimized arc-extinguishing chamber structure, combined with high-performance arc chute plates, significantly reduces arc extinction time to ensure rapid circuit interruption during fault conditions. The spring-operated mechanism enables manual quick-make/quick-break operations with responsive tripping reliability.
Designed for 80A rated current capacity, the three-pole configuration meets three-phase power distribution requirements. Compact dimensions (108mm×90mm×75mm) allow flexible installation in standard distribution cabinets, while rail-mounted design simplifies installation procedures. Suitable for switchgear protection in power substations, industrial manufacturing workshops, commercial complexes, and residential buildings, particularly effective for circuit protection of motors, transformers, and other electrical equipment.
Practical design features include a transparent protective cover for visual status indication, reserved auxiliary shunt trip interfaces for functional expansion, and a mechanical endurance exceeding 20,000 operations to reduce maintenance frequency. With robust environmental adaptability, the device maintains stable performance within -25℃ to +70℃ temperature range, meeting deployment requirements across various climatic conditions.
