The VS1-12(VBM7) vacuum circuit breaker adopts a fixed structure design, primarily used in fixed switchgear installations. This high-performance circuit breaker is engineered for controlling and protecting transmission and distribution lines with exceptional reliability.
With its robust construction, the VS1 vacuum circuit breaker can operate frequently within its current range and interrupt short circuit currents multiple times. The device boasts an impressive mechanical life of 30,000 operations and can break full capacity short circuit current up to 50 times.
This circuit breaker is particularly suitable for reclosing operations, offering high operational reliability and extended service life. The general type features vertical insulators for climate protection, requiring minimal maintenance - typically only periodic cleaning or lubrication.
The pole type variant utilizes a solid insulation structure with integrated sealed poles, achieving maintenance-free operation. The VS1 vacuum circuit breaker can be installed in either stationary or extractable configurations within switching cabinets, or mounted on frames as needed.
The innovative permanent magnet actuator maintains the core position without mechanical locking. When activated, the combined magnetic fields from the coil and permanent magnet create the necessary force to operate the switching mechanism at specified speeds. This bistable structure ensures reliable operation with minimal energy consumption.
