10kV MV Indoor Vacuum Circuit Breaker/VCB for Switchgear, VAC83-12kV

1. General description
  VAC83 indoor vacuum circuit breaker is a new type of switch device, which is mainly used in three-phase AC power system with rated voltage of 12kV, and rated frequency of 50-60Hz. It has the advantages of compact structure, high reliability, small operation vibration and easy maintenance. It can be widely used in power plant, steel plant, metallurgy, petrochemical, transportation, building and other industrial and mining enterprises as a switch device for protection of high voltage motors, transformers, line faults and other loads.

The Technical Specifications of this vacuum circuit breaker define its electrical and mechanical parameters for indoor medium-voltage switchgear applications. The indoor vcb model VAC83-12kV (550mm Cabinet) is a new type of switch device mainly used in three-phase AC power systems with rated voltage of 12kV and rated frequency of 50-60Hz. This indoor vacuum circuit breaker features a compact structure, high reliability, small operation vibration, and easy maintenance, making it widely applicable in power plants, steel plants, metallurgy, petrochemical, transportation, building, and other industrial and mining enterprises as a switch device for protection of high voltage motors, transformers, line faults, and other loads. This cabinet vcb achieves full modular design with integrated and optimized functionality, featuring only more than 70 parts in the overall mechanism with no adjustment links, minimizing maintenance requirements. The indoor vcb includes a manual energy storage handle and allows fast replacement of wearing parts without special tools. Each vacuum circuit breaker has passed the 72-hour salt spray test verification. This indoor vacuum circuit breaker employs friction-type opening structure with minimal wear and failure rate. Proper installation of this cabinet vcb ensures reliable protection in 12kV distribution systems.
