ZN63S(VS1+)-12 Series
Indoor High Voltage AC Vacuum Circuit Breaker

Environmental Conditions:

Surrounding air temperature: upper limit +40ºC, lower limit -15'ºC, daily average not exceeding +35'ºC;
Relative humidity of the air: daily average not exceeding 95%, monthly average   not exceeding 90%;
Altitude: ≤ 2000m;
Installation site: It should be a place without fire, explosion hazard, corrosive gas, and severe vibration.

lf users have special requirements, they should provide detailed explanations when placing an order.
 

This indoor high voltage AC vacuum circuit breaker is designed for medium voltage switchgear, distribution cabinets and feeder protection systems. It is used for load switching, fault current interruption and protection control, supporting reliable operation in indoor power distribution and substation applications.

High lifespan:Mechanical lifespan 30000 times, full capacitly short-circuit current breaking times 50 times, can perform freguentoperations or break short-circuit current multiple times within the working current range;

High reliability: Suitable for reclosing operations with various characteristics and can replace imported VD4;
All working conditions: Adopting a vertical insulation cylinder to defend against various special environmental impacts;

Maintenance free: Adopting solid insulation structure - integrated solid sealed pole;
Fuly functional and versatile: Can be installed in a fixed or removable manner, and can also be installed on a frame for use;

Standardized desian: Good interchangeabilty and strong, universality, especially suitable for KYN2B (GZS1) indoor midmounted high-voltage switchgear.
