Description:Product Name: High Voltage Indoor Vacuum BreakerModel Number: VH3 SeriesPlace of Origin: ChinaThe VH3 vacuum breaker has a special spring actuator, is suitable for frequent operation, and has a lifetime of 30,000 actuations. Very little maintenance is required, simply requiring cleaning of the breaker and lubrication of the rotating parts. Machine layout facilitates inspection and maintenance, and two stage switch-off trip makes switch-off easier. In order to solve the problem of longitudinal magnetic field vacuum quenching pots requiring higher primary breaking speeds, the VH3's contact springs are designed to be installed in a support frame under the main circuit; which thus enables elastic potential energy stored when the contact spring switches on to be exerted directly on the moving conductive rod in the quenching pot during switch-off. This model's simple design helps to increase the breaking speed, while the special guiding device protects the quenching pot against lateral force, therefore increasing the electric life of the breaker.
