VHS2-12 series indoor high-voltage AC vacuum circuit breaker (solid sealed pole)Detailed product description：

The VHS2-12 series solid sealed circuit breaker is mainly used in 10kV three-phase power systems with a rated frequency of 50Hz, as a protective and control electrical device. Its design meets the requirements of standards such as GB1984, JB/T3855, DL/T403, IEC62271-100, etc. The overall structure adopts the form of an operating mechanism box and an arc extinguishing chamber arranged in front and behind. The main electrical circuit pole part adopts a fixed sealing insulation method, which is different from the insulation cylinder structure. It seals the vacuum arc extinguishing chamber and conductive connectors with epoxy resin through a special process to form the pole. This series of circuit breakers is mainly used for mid mounted switchgear (KYN type) and can also be used for fixed switchgear (XGN type). It has wide compatibility and interchangeability, and can be easily interchanged with mainstream domestic circuit breakers in a handcart style.

The main technical performance of VHS2-12 series indoor high-voltage AC vacuum circuit breaker (solid sealed pole) is as follows:

Rated voltage: 12 kV
Rated current: 630A~4000A
Rated short-time (4s) withstand current: 20 kA to 40 kA
Rated short-time (60s) power frequency withstand voltage: 42 kV (universal value); 48 kV (isolated fracture)
