Problems solved by technology

[0002] In the field of communication and electric power, the miniature circuit breaker actuator is a key component to ensure the safety of electricity consumption and circuit switching. Most of these fields have automatic control rooms, that is, unattended. On and off of the miniature circuit breaker, once the miniature circuit breaker executive device does not execute the command operation or does not open and close accurately within the specified time after receiving the command, it may cause misjudgment by the remote operator, resulting in huge Loss

Especially for remote control, once encountering unstable phenomena such as interruption, delay or interference of the command sending system, the miniature circuit breaker actuator will not be able to accurately control the miniature circuit breaker, which will eventually lead to the failure of the miniature circuit breaker to open and close. In severe cases, it will cause equipment damage or burn out of the entire circuit, causing major economic losses to the manufacturer.

In addition, there is also a driving device in the miniature circuit breaker actuator, such as a motor. Once the motor is burned out due to excessive current or the switch is not in place, the miniature circuit breaker actuator cannot be used to control the on-off of the miniature circuit breaker.
