PRODUCT DETAILS
The installation volume is small, the structure is safe and reliable, and there are multiple solutions for upper isolation and lower isolation. The switch adopts vacuum arc extinguishing method, and the material recycling and degradation rate reaches more than 95%. Free of sulfur hexafluoride (SF6) greenhouse gas and solid epoxy resin waste, it has significant energy saving and emission reduction effects, and is in line with the national green power development concept. It is equipped with an air-insulated sealed box and has stronger environmental adaptability. It is suitable for China's vast territory and regions. Significantly different and complex power distribution operating environments.
Product performance complies with the requirements of GB1984-2014 "AC High Voltage Circuit Breaker" E2-M2-C2 class circuit breaker
