1. Vacuum arc extinguishing, strong breaking capacity, long electrical life and 10,000 mechanical life; 2. Simple structure, maintenance-free, long maintenance period; 3. Good insulation performance and strong anti-pollution ability; 4. It can be equipped with spring or electromagnetic operating mechanism, with reliable mechanical performance and frequent operation; no fire and explosion hazard; 5. Built-in current transformer, the lecturer's precision reaches 0.2, which can realize three-phase interactive protection; 6. With condensation controller, it can keep the circuit breaker running reliably under certain temperature and humidity.
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.
