Description
The vacuum circuit breaker Model MZN20-500 is suitable to exchange 50HZ, the nominal voltage is to 1140 KV. Rated current to the industrial and mining enterprises of 500A, the power plant, the combination of converting station and frequent operation.
Used mainly in the using of protection and control of the electrical apparatus. In being vacuum in stylus for medium, therefore, its volume little, withstand voltage is high, breaking is high in ability, have long performance life, stylus needn’t maintenance, especially because its electric arc is not exposed, safe and reliable advantage, it is industrial sectors such as coal, electricity, chemical industry, metallurgy, petroleum, etc.
