Medium Voltage Power Circuit Breakers

New and reconditioned medium-voltage power circuit breakers manage and protect medium-voltage networks. They identify faulty conditions and disrupt current to prevent damage to electrical equipment. Medium-voltage breakers also serve as switches to control electrical flow during maintenance and system changes.

Functions of Reconditioned and New Medium Voltage Power Circuit Breakers

Medium-voltage circuit breakers typically operate between 1 kV and 72.5 kV on commercial and industrial installations and power distribution networks. They detect faults such as short circuits or overloads and stop the flow of current.

Air circuit breakers: These breakers are suitable for low-medium voltage and use air as an insulating medium
SF6 breakers: SF6 uses sulfur hexafluoride gas to stop arcing
Vacuum circuit breakers (VCBs): These are common in industrial and utility applications. They use a vacuum to extinguish arcs. VCBs are compact, reliable, and require little maintenance.

Medium Voltage circuit breakers reduce the risk of electrical fires and protect equipment from damage related to arcing and overloads. They are common in commercial facilities, such as hotels, offices, malls, and hospitals.
