VTZ-12/1250-25 type Vacuum Circuit Breaker uses composite insulated material, so it does not have pollution and explosion problems.With particular advantages, it is suitable for some network where there is high switch frequency in the working current range or where repeatedly short circuit breaking operations happen.VTZ-12/1250-25 type vacuum circuit breaker can be used as individual units for Switchgear type KYN28, AMS, GZS1, ZS1,Unigear and so on.
VTZ-12/1250-25 vacuum circuit breaker, vacuum, when the dynamic and static contact in the Operating mechanism under the action of electric trip, the contact will produce a vacuum arc, and because of the special structure of the contact, the gap in the contact Also produce the appropriate longitudinal magnetic field, to promote the vacuum arc to maintain the diffusion type, and make the arc evenly distributed in the contact surface combustion, to maintain a low arc voltage, current zero crossing, the residual ions, electrons and metal vapor in the micro Sec order of magnitude within the time can be compounded or gathered in the contact surface and shield, interrupter dielectric fracture strength of the fracture is quickly restored, so the arc was extinguished to achieve the purpose of breaking, the vacuum circuit breaker using magnetic field control Vacuum arc, which has a strong and stable breaking current capacity.
