CDM6I-630L/4300A 400A Molded Case Circuit Breaker Technical Overview
The CDM6I-630L/4300A 400A molded case circuit breaker is an intelligent protection device developed for power distribution systems, designed for electrical networks with AC 50Hz frequency and rated operational voltage up to 400V. Featuring modular construction, this product provides precise overload and short-circuit protection functions to ensure safe operation of electrical circuits and connected equipment.
With its innovative bimetal thermal-magnetic trip mechanism, the device can detect abnormal current within milliseconds and execute breaking actions. The 630A frame current design offers excellent scalability, allowing flexible adjustment of protection parameters according to practical requirements. The 4300A high breaking capacity ensures reliable fault current interruption under extreme short-circuit conditions, effectively minimizing operational risks. The 400A rated current configuration meets protection demands for main power lines in medium-sized industrial switchboards, commercial complexes, and public infrastructure.
Constructed with high-strength engineering plastic housing, the product demonstrates excellent heat resistance and impact tolerance. The silver-alloy contact system enhances electrical conductivity while reducing energy loss. Compact dimensions optimize cabinet space utilization, supporting both vertical and horizontal wiring configurations. The integrated visual status indicator window and ergonomic manual operating handle provide intuitive condition monitoring and convenient field maintenance.
This solution is particularly suitable for application scenarios requiring high power supply continuity, including manufacturing facilities, data centers, and rail transit systems. The optimized arc chute structure significantly reduces arc energy during breaking operations, thereby extending service life. Standardized accessory interfaces allow expansion of auxiliary functions such as undervoltage protection and shunt trip modules. Its compatibility with intelligent monitoring systems enables remote status tracking and energy management.
