CDM1-250L/3300 200A Plug-in Type Molded Case Circuit Breaker (Front-mounted Terminals)
The CDM1-250L/3300 200A molded case circuit breaker is a modular protection device designed to deliver reliable circuit control and overload protection for low-voltage distribution systems. Featuring high-strength insulated materials and a compact structural design, it ensures operational safety while optimizing space utilization in electrical enclosures. The front-mounted terminal configuration combined with plug-in installation architecture allows flexible layout planning and facilitates efficient maintenance by technicians.
Equipped with a thermal-magnetic trip mechanism, the device accurately detects abnormal currents including overloads and short circuits, achieving circuit interruption within 15 milliseconds. The 200A current rating meets protection requirements for main power lines in commercial and industrial applications, with its 3-pole 3300-series configuration being particularly suitable for three-phase AC distribution networks. The contact system employs silver-alloy materials paired with an optimized arc-extinguishing chamber, enhancing electrical endurance and breaking consistency. The IP40-rated enclosure provides effective dust protection for diverse operating environments.
The plug-in design enables live replacement through secure rail-mounted installation, significantly reducing system downtime during maintenance. Front-access terminals feature dual-screw clamping mechanisms compatible with conductors up to 25mm², offering ergonomic wiring space for standardized tool operation. A mechanical status indicator provides clear ON/OFF visualization, complemented by a manual test button for periodic functional verification.
This product series is widely implemented in industrial plants, commercial complexes, and public infrastructure for critical protection roles including motor circuits, distribution cabinet main switches, and capacitor compensation systems. Its stable performance characteristics contribute to enhanced electrical safety and operational continuity in power supply networks.
