The VH2 indoor high-voltage vacuum breaker was developed specifically with
a large quantity of vacuum quenching pots and a compact longitudinal
magnetic field based on original VH1 Siemens technology.

The VH2 vacuum breaker has been redesigned with a middle sealing compact
longitudinal magnetic field vacuum quenching pot, and features chromium
copper contacts and cotyloid longitudinal magnetic field construction with
strong breaking capacity, short arcing time and long electric life.

Model VH2 products have a relatively high price/performance ratio under
equal specification parameters, thus enabling reduction in users' costs.

Having developed two small capacity (20kA and 25kA) vacuum breakers, we can
also design and manufacture products with multiple phase-to-phase distances
including 210, 230, 250 and 275mm to facilitate switching between cabinets
of different types.
