Product Description

Product Description

This type of vacuum circuit breaker is an integral type of fully sealed high-voltage switchgear with compact size and small volume. The vacuum circuit breaker is suitable for power systems with rated voltage 7.2~24kV, three-phase, AC 50/60Hz. It is suitable for frequent operation for protection and control of lines and electrical equipment. The products comply with IEC62271-100 and GB1984 standards and have passed the type test.

Main Features

1. The vacuum circuit breaker adopts the design of upper arc extinguishing chamber and lower operating mechanism, which is easy to adjust;

2. Adopting the structure combining air and organic composite insulation material;

3. Simple spring-operated mechanism, 10,000 operations;

4. Good self-locking performance due to the screw propulsion mechanism.
