CNKA Motor Circuit Breaker box FAQ

Q: What is the difference between a motor circuit breaker and a circuit breaker?

A: Motor protection circuit breakers are specialized devices designed for motor protection, allowing users to preset the exact motor size for precise protection. Unlike standard miniature circuit breakers (MCBs), motor protection circuit breakers offer advanced features and settings tailored for industrial motor starting applications. They provide superior protection against overloading, short circuits, and other electrical faults, which helps reduce downtime and extend equipment lifespan.

Q: What type of circuit breaker is suitable for a motor?

A: The CNKA Motor Protection Circuit Breaker (MPCB) is an electro-mechanical device designed to protect motors from irregular current flow, including overloads, unexpected interruptions, and phase imbalances. It offers protection against phase loss and line faults, making it ideal for safeguarding 3-phase motors.

Q: Why is an MCB not suitable for motor protection?

A: MCBs are not ideal for motor protection because they lack sensitivity to phase failures. During a phase failure, a motor can experience a surge of current in the remaining phases, leading to overheating and potential damage to the winding. Motor protection circuit breakers are specifically designed to handle such issues and provide better protection for motors.
