CDM1-250L/42002 Molded Case Circuit Breaker 250A Product Introduction
Product Overview:
The CDM1-250L/42002 molded case circuit breaker is an intelligent protection device designed for low-voltage distribution systems, suitable for AC 50Hz power networks with rated operational voltage up to 690V. Featuring a modular structure design, this product provides comprehensive circuit protection by rapidly interrupting overload and short-circuit faults, ensuring reliable operation of electrical equipment. Its compact enclosure combines installation convenience with space efficiency, making it adaptable to industrial control cabinets, building power distribution systems, and public facility power supply networks.
Key Features:
- The optimized contact system utilizes silver alloy materials and multi-layer buffer design to reduce arc energy, enhancing breaking efficiency and electrical durability. Balanced contact pressure technology ensures stable contact resistance and minimized energy loss.
- Modular arc chute structure incorporates metal grids and gas diversion channels for rapid arc splitting and cooling. Generated ionized gas is directionally discharged through independent exhaust channels, significantly improving operational safety.
- Innovative mechanical transmission mechanism adopts 3D motion optimization design to ensure synchronized contact movement. The operating handle provides clear three-position indication (ON/OFF/TRIPPED) for convenient status monitoring and maintenance.
- Thermal-magnetic trip unit integrates bimetal strip and electromagnetic coil dual-sensing system, delivering precise long-delay overload protection and instantaneous short-circuit protection. Adjustable dial enables continuous current setting calibration for diverse load requirements.
- IP40 protection rating is achieved through high-strength engineering plastic and flame-retardant composite housing. Internal isolation barriers effectively prevent foreign object intrusion and interphase arc propagation.
