ZK1-630/1140 AC low-voltage vacuum circuit breaker is suitable to exchange 50HZ, the nominal voltage is to 1140V.
Rated current to the industrial and mining enterprises of 630A, the power plant, the combination of converting station and frequent operation. Used mainly in the using of protection and control of the electrical apparatus. The stylus is in the vacuum medium, therefore, its volume is small, the high, breaking ability of withstand voltage is high.
The vacuum circuit breaker is suitable to exchange 50 HZ, the nominal voltage is to 1140 V. rated current to the industrial and mining enterprises of 630A, the power plant, the combination of converting station and frequent operation. Used mainly in the using of protection and control of the electrical apparatus.
It is in stylus at medium vacuum, 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.
