Product Introduction
Structure: It is composed of a frame, contact arms, high-voltage fuses, propulsion mechanism and secondary contacts. The frame provides support, the fuse is the core protective component, and the propulsion mechanism realizes position switching.
Principle: Conduct the current circuit during normal operation; When the circuit is overloaded or short-circuited, the fuse element melts and extinguishes the arc, cutting off the circuit.
Function: It has short-circuit and overload protection capabilities, and can also form a clear disconnection point through isolation positions to ensure maintenance safety.
Application: Widely used in industrial and mining enterprises, power plants, substations and civil power supply systems to control and protect power equipment.
