Product Description

ZN12-12/1250-31.5`s mechanism and vacuum interrupter are designed to be a whole. Specialized 3AF type spring operating structure from Siemens can be operated by manual or carry out direct current energy saving operation. It`s can be designed as 210mm,230mm,250mm,275mm and other kinds of phase space, which matches better with different kinds of Switchgear.


The working principle of the Vacuum Circuit Breaker is: When the moving and static contact in the Operating mechanism under the action of the gate, the contact between the arc, the contact surface at high temperature volatile steam, the contact design for the special shape, Through the magnetic field generated when the arc under the action of the magnetic field along the contact surface tangential direction of rapid movement in the metal cylinder (shield) on the condensation of some metal vapor, the arc in the natural zero-crossing, the contact between Medium strength and quickly recover.
