50Hz SF6 Circuit Breaker High Voltage Vacuum Type For High Altitude Environment

VSK-type indoor high voltage vacuum circuit breaker,SF6 Circuit Breaker

1. Overview

The VSK vacuum circuit breaker is designed with high vacuum, reliable insulation performance and excellent arc extinguishing ability, and has the characteristics of small size, light weight, long life and flame retardant. Under normal conditions of use, as long as it is within the technical parameters of the circuit breaker, it can ensure safe and reliable operation in the power grid of the corresponding voltage level.
VSK vacuum circuit breakers can perform frequent operations or break short-circuit current multiple times within the working current range; the mechanical life can be as high as 30,000 times, and the number of full-capacity short-circuit current breaking times can reach 50 times.
The installation form of VSK vacuum circuit breaker in the switch cabinet can be either a fixed type or a drawable type, and it can also be installed on the frame for use.
The product complies with GBl984, JB3855, DL402/403, lEC60056 and other relevant standards.
