CDM1-250M/4340 Molded Case Circuit Breaker Introduction
The CDM1-250M/4340 series molded case circuit breaker is designed for low-voltage distribution systems, providing reliable circuit protection under 220V AC environments. With a rated current of 225A, this modular device delivers effective overload and short-circuit protection to ensure safe operation of electrical circuits.
Featuring a high-strength insulated housing, the breaker integrates precision electromagnetic trip mechanisms and advanced arc extinguishing systems. Its rapid response mechanism can complete circuit interruption within milliseconds when detecting electrical faults, effectively preventing accident escalation. The compact modular design reduces installation space requirements by approximately 30%, supporting versatile vertical or horizontal mounting options for space-constrained distribution cabinets.
Equipped with an intuitive mechanical status indicator window, the breaker provides clear open/close position visualization. The ergonomic operating handle offers moderate switching torque for convenient manual operation during maintenance. Specially alloyed copper contacts maintain stable conductivity through precision machining, ensuring low contact resistance even after prolonged service.
This product series is suitable for industrial production lines, commercial building power distribution systems, and public facility power networks. It demonstrates particular effectiveness in motor protection, transformer secondary circuits, and distribution trunk line protection. Through compatible accessory configurations, extended functions such as remote signaling and electrical interlocking can be achieved.
Usage Guidelines:
- Select appropriate specifications based on actual load characteristics
- Ensure secure terminal connections during installation
- Recommended periodic functional testing
- Always disconnect upstream power before maintenance
