ป้องกันความร้อนของมอเตอร์

A motor thermal circuit breaker is an electrical switch that is automatically operated and is designed to protect an electrical circuit from excess current or short-circuiting. A motor thermal circuit breaker’s main function is to interrupt current flow if a fault is detected. Ranging in size, china circuit breakers offer thermal protection and magnetic-hydraulic trip-free operation and can protect something as small as a household appliance or be a switchgear that protects high voltage circuits for an entire city.
