General

VS1-24 indoor high voltage handcart vacuum circuit breaker is suitable for three-phase, AC50Hz with 24KV rated voltage.It can provide control and protection for industrial and mining enterprises, power plants and substations and is especially suitable for high-altitude areas where important loads are interrupted and a place needs frequent operations.

lt complies with GB1984-2003 “AC high voltage circuit breaker”, DL/T403-2000 “3.6-40.5KV indoor vacuum circuit breaker ordering technic conditions” and related IEC standards, and has reliable interlocking function.

The operating mechanism of the circuit breaker is spring energy storage type, which can be operaled by AC or DC energy storage, or can b manually operated.

The circuit breaker can also be equipped with a long-life permanent magnet operating mechanism, which can have a mechanical life of 60,000 times and can be used in the occasion with frequent operation.

The circuit breaker is designed in the form of front and rear sub-mounting structure, which can be used either as fixed mounting unit or as intermediate unit with chassis.
