Key Specification

Our circuit breaker has the followingcharacteristics: contact opening distance is small, long mechanicallife. Short arcing time recovery speed, off-off line faultperformance. Wear smaller, electrical contacts, long life, lownoise suitable for frequent operation. Small size and lightweight.
Vacuum circuit breaker works: When dynamic and static contact underthe action of the operating mechanism sub-gate, the contact betweenthe arcing contact surface evaporate out of steam at a hightemperature, due to the special shape of the contact design, in thecurrent when generating a magnetic field through the arc in thismagnetic field along the contact surface tangentially rapidmovement in the metal cylinder (shield) metal vapor condenses onthe part of the arc in the natural zero crossing went out, contactbetween the dielectric strength and quickly recover.
