Power Intelligent 400V 5000 Times Low Voltage Circuit Breaker 630A Vacuum
Overview of power Intelligent 400V 5000 Times Low Voltage Circuit Breaker 630A Vacuum
The contact of the circuit breaker is maintenance free, has strong overload capacity, strong breaking and arc extinguishing capacity, and can realize real zero arcing. The circuit breaker has outstanding environmental capacity, and the design ambient temperature can reach - 40 ℃, and the altitude is more than 2000 meters. It is especially suitable for places where air circuit breakers are not suitable for use, such as electrical equipment in flammable and explosive industries such as wind power generation, coal mine, chemical industry and metallurgy. At the same time, it is suitable for power distribution in residential areas with high safety requirements.
