AC Load Breaker Switch

AC Load Breaker Switch is an electrical device used to control the on-off of current in an AC circuit and protect the safety functions of the circuit and equipment. It can automatically or manually cut off the circuit when there is an anomaly in the circuit (such as overload, short circuit, etc.), so as to prevent the occurrence of equipment damage and fire and other safety accidents.

Zi Kai AC Load Breaker Switch Application

Industrial production line: In a highly automated industrial environment, the AC Load Breaker Switch plays a crucial role in precisely regulating the power supply of the motor power source and lighting system, and once any abnormal conditions are detected, the operation is immediately executed, thus effectively safeguarding the safety of the entire production line.

Power system: In the power transmission and distribution network, the AC Load Breaker Switch is not only the hub of power distribution, but also the strong backing of the security line. When the circuit is attacked by a fault, it can respond quickly, cut off the propagation path of the fault current, and effectively curb the spread and expansion of potential accidents.

Building power distribution: Whether it is a bustling commercial building or a warm residential building, AC Load Breaker Switch is an integral part of its power distribution system. It accurately manages the power supply of each floor and each room, and provides a solid guarantee for electrical safety in the building through the built-in overload and short circuit protection mechanism.

New energy field: In solar, wind and other new energy power generation systems, AC Load Breaker Switch is used to control the output and cut-off of electric energy to ensure the safe operation of power generation equipment and power grid.
