English Introduction
The CDM3-400N/4300B 400A molded case circuit breaker is a high-performance electrical protection device introduced by Delixi Electric. This circuit breaker is equipped with a thermal-magnetic trip unit, which provides reliable overload and short-circuit protection. With a rated current of 400A and a frame rating of 400A, it has an ultimate short-circuit breaking capacity of up to 50kA, making it suitable for high-load electrical circuits.
In terms of design, the CDM3-400N/4300B 400A circuit breaker features excellent electrical and mechanical properties. The contact system has been optimized to ensure stable contact resistance and low energy consumption during long-term operation. The operating mechanism of the circuit breaker is flexible and reliable, supporting manual operation. The well-designed operating handle allows users to quickly perform opening and closing operations.
Additionally, this circuit breaker has an isolation function. The isolation position corresponds to the “OFF” position, and the operating handle can only indicate the “OFF” position when the contacts are truly open. This design effectively prevents safety hazards caused by accidental operations and ensures the safety of the electrical circuit.
The CDM3-400N/4300B 400A molded case circuit breaker is suitable for a wide range of applications, including industrial equipment, commercial buildings, residential housing, and infrastructure projects. It provides stable protection for electrical circuits, preventing damage to equipment and fire risks caused by overload or short circuit. Its broad application scope and reliable performance make it an ideal solution for electrical protection.
