VS1(ZN63)-24

INDOOR HIGH VOLTAGE VACUUM
CIRCUIT BREAKER

Overview
VS1 (ZN63) -24 series indoor high-voltage vacuum circuit breakers are indoor high-voltage switchgear with rated voltage of 24kV and three-phase AC
50Hz, suitable for the control and protection switches of power transmission and distribution systems such as power plants, substations and industrial
and mining enterprises. , Especially suitable for high-altitude areas to break important loads and frequent operations.
The manufacture of circuit breakers complies with China's national standards GB1984-2003 "AC high-voltage circuit breakers", DL / T403-2000 "3.6 ~
40.5kV indoor vacuum circuit breaker ordering technical conditions" and related IEC standards, and has a reliable interlocking function.
The operating mechanism of the circuit breaker is a spring energy storage type, which can be operated by AC or DC energy storage or manually.
The circuit breaker can also be equipped with a long-life permanent magnet operating mechanism, and the mechanical life can reach 10,000 times. It
can be used in extremely frequent operations.
The circuit breaker is designed as a front-rear sub-assembly structure, which can be used as a fixed installation unit, or can be used as a center-mounted
unit with the chassis.
