A circuit breaker is an automatic electrical switching device that is mainly used to protect equipment and lines in electrical systems from hazards caused by faults such as overload, short circuit, and leakage.
The built-in linkage shaft of the handle of each pole of the circuit breaker is an important mechanical component in the multi-pole circuit breaker, which is used to ensure that the handles of multiple poles (such as three-pole or four-pole) move synchronously during operation, so that all poles can break or close the circuit at the same time.
The linkage shaft is usually designed to be simple for easy installation and maintenance. Its core function is to drive multiple poles to operate simultaneously by rotating or sliding.
The maintenance of IoT intelligent leakage circuit breakers is essential to ensure the safe operation of electrical equipment and extend its service life. Here are some key maintenance measures...
The shell material of the external circuit breaker of the energy meter usually needs to have good durability, electrical insulation performance and corrosion resistance to ensure that the circuit breaker is safe and reliable in complex working environments.
