Product overview

VS1 vacuum circuit breaker can perform frequent operations or break short-circuit current multiple times within the working current range; the mechanical life can be up to 30,000 times, and the full-capacity short-circuit current breaking times can be up to 50 times.

VS1 vacuum circuit breakers are suitable for reclosing operation and have extremely high operational reliability and service life.

VS1 vacuum circuit breaker (common type) adopts a vertical insulating cylinder to prevent the influence of various climates; and in terms of maintenance and maintenance, it is usually only necessary to occasionally clean or lubricate the operating mechanism.

The VS1 vacuum circuit breaker (pole type) adopts a solid insulating structure-integrated solid-sealed pole, which realizes maintenance-free.

The installation form of VS1 vacuum circuit breaker in the switch cabinet can be either fixed or withdrawable, and can also be installed on the frame for use
