Model Description

Product technical parameters and external dimensions

Product structure features

1.It is equipped with CT23 type spring energy-stored operating mechanism. Energy-stored, opening and closing can be achieved by motor or by manual.
2. ZW8-12 (FG) consists of ZW8-12 breaker and isolator, called combined breaker, can be used as sectionalizer.
3.The structure of breaker is of three-phase assembled in a tank, three-phase vacuum arc-extinguishing chamber enclosed in metal tank, insulation material between phases and phase to each made of SMC.
4. Reliable performances, and high insulating strength.

Environment condition

1. Ambient air temperature: -5~+40 and the average temperature should not exceed +35 in 24h.
2. Install and use indoors. Altitude above sea level for operation site should not exceed 2000M.
3. Relative humidity should not exceed 50% at max temperature +40. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20. But in view of the temperature change, it is possible that moderate dews will produce casually.
4. Installation gradient not exceed 5.
5. Install in the places without fierce vibration and shock and the sites insufficient to erode the electrical components.
6. Any specific requirement, consult with manufactory.
