The ZN63(VS1)-12 type indoor high-voltage vacuum circuit breaker is an indoor switchgear for 12kV power systems, suitable for three-phase power systems with a rated voltage of 12kV and a frequency of 50Hz. It is used as a protective and control electrical appliance, and is especially suitable for places requiring frequent operation or multiple short-circuit current interruptions.
Product types include multiple variants such as handcart type, fixed type, side-mounted type, permanent magnet type, and fixed pole type.
The ZN63A(VS1)-12 type indoor AC high-voltage vacuum circuit breaker has a rated voltage of 12kV and a rated frequency of 50Hz. Its rated current covers 630A, 1250A, 1600A, 2000A, 2500A, 3150A, 4000A, etc., and its rated short-circuit breaking current includes 20kA, 25kA, 31.5kA, 40kA. This circuit breaker has a mechanical life of up to 30,000 operations and can achieve 50 short-circuit current breaking operations at full capacity. Its normal operating environmental conditions include: ambient temperature not higher than +40℃ and not lower than -15℃ (can reach -30℃ during storage and transportation), altitude not exceeding 1000m (special design can reach 4500m), daily average relative humidity not exceeding 95%, monthly average relative humidity not exceeding 90%, seismic intensity not exceeding 8 degrees, and the installation site shall be free of fire, explosion hazards, severe pollution, chemical corrosion and severe vibration. The secondary control voltage can be selected as DC220V, AC220V, DC110V or AC110V, and anti-jump devices, interlocking devices, overcurrent devices, etc. can be configured. Installation forms include fixed type, handcart type (withdrawable type) and frame type. The model of this series of products usually follows the naming rule of "VS1-12/rated current-rated short-circuit breaking current". The main models include: VS1-12/630-20, VS1-12/630-25, VS1-12/630-31.5; VS1-12/1250-20, VS1-12/1250-25, VS1-12/1250-31.5; VS1-12/1600-25, VS1-12/1600-31.5, VS1-12/1600-40; VS1-12/2000-25, VS1-12/2000-31.5, VS1-12/2000-40; VS1-12/2500-25, VS1-12/2500-31.5, VS1-12/2500-40; VS1-12/3150-25, VS1-12/3150-31.5, VS1-12/3150-40; VS1-12/4000-25, VS1-12/4000-31.5, VS1-12/4000-40.
