  • What is a miniature circuit breaker? - Quisure

    Undervoltage protection uses undervoltage trippers in the structure of miniature circuit breakers to monitor the fluctuation amplitude of operating voltage. When voltage drops to 70% to 35% of rated voltage or a fault occurs, it feeds back to the circuit breaker and immediately performs a breaking action, which prevents the circuit breaker from closing if the voltage falls below 35%.
