Product overview

VS1-12 series "high voltage vacuum circuit breaker" is named because the arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are high vacuum; the vacuum circuit breaker has small size, light weight, suitable for frequent operation, extinguishing The advantage of the arc without maintenance is more popular in the distribution network.
