ZW32-15 Circuit Breaker

To switch on/off load current, over-loading current and short-circuit current in the electrical To switch on/off load current, over-loading current and short-circuit current in the electrical system; for protection and control in transformer substation and distribution system in industrial and mine enterprise.State-of-art international insulator sealing technology is adopted to equip the product with outstanding outdoor conditions endurable ability. The contradiction of compact vacuum quenching pot to meet the requirement of insulation is fully solved. And therefore it's in extensive application. The product is light, compact, good-looking and is able to realize intelligent network distribution.
