Product Description

ZN63A(VS1)-12 indoor high voltage vacuum circuit breaker, is a three-phase AC 50Hz rated voltage of 12kV power system indoor switchgear, as a power grid equipment, industrial and mining enterprise power equipment protection and control unit. lt is suitable for places that require frequent operation under rated operating current, or multi-switch short-circuit current.

The circuit breaker adopts the integrated design of the operating mechanism and the circuit breaker body, which can be used as a fixed installation unit, or it can be equipped with a special propulsion mechanism to form the function of the handcart unit.

Ambient temperature: not higher than +40ºC , not less than -15 °C (storage and transportation at -30 °C is not allowed); Altitude: not more than 1000m; Relative humidity: daily average is not more than 95%, monthly average is not more than 90%,saturated vapor pressure average is not more than 2.2 x10-3MPa; The monthly average is not more than 1.8x 10-3MPa; Seismic intensity: not more than 8 degrees; No fire, explosion, serious pollution, chemical corrosion and severe vibration of the place.
