Product Description

VSG-24 Indoor High Voltage Vacuum Circuit Breaker (Modular) is our latest medium-voltage vacuumcircuit breaker product, which is

suitable for air-insulated indoor switching systems. The circuit breakeradopts the new solid-sealed pole technology with a modular

mechanism. At the same time, the circuitbreaker has perfect mechanical and electrical interlocking functions, and can be widely used

in energy.industry, construction, infrastructure and other fields.

The circuit breaker can perform frequent operation within the operating current range or open the shortcircuit current multiple times;

The mechanical life can be up to 30,000 times, and the number offullcapacity short-circuit current breaks can reach 50 times.

Circuit breakers are suitable for reclosing operations and offer high operational reliability and servicelife.

The circuit breaker can be installed in the switchgear ither as fixed or withdrawable or mounted on aframe.
