Product Description

Product Description

 

overview

The product has excellent breaking performance. It adopts compressed air arc chamber with long electric life. It can continuously break 40ka short circuit current for 20 times underrated voltage without maintenance or replacement of sulfur hexachloride gas. It has high mechanical reliability and mechanical life of more than 10000 times. It can be operated frequently; Each set can be equipped with 12 current transformers for users to choose. The product adopts a new type of MKZMSF6 pointer densimeter, and the reading of the pressure gauge is not affected by the temperature change, so it is easy to use
This type of circuit breaker is a three-phase AC50 Hz outdoor high-voltage electrical equipment, which is suitable for the control and protection of 40.5 kV power distribution system. It can also be used for connecting circuit breaker and switching capacitor bank. This product is equipped with CT14 spring machine. The circuit breaker meets the requirements of national standaroGB1984-1989 "AC high voltage circuit breaker" and IEC 56, IEC 62271-100 "high voltage AC circuit breaker".
