LW**2.5 TO **2KV series SF6 circuit breakers are designed with latest development of self-energizing theory that the arc generated in the chamber is distinguished at a specified time with a part of energy from the arc itself. The arcing chamber of LW*5 is so constructed on the basis of resent research of electric and gas flow field that high arc quenching efficiency and operation reliability is achieved. The force needed outside for breaking operation of the circuit breaker is greatly reduced for the arc itself contributes one part of energy used for arc clearance, and application of compact spring operating mechanism becomes reality Voltage rating kV *2.5 **6 **5 **0 Current rating A ***0 Rated gas pressure (SF6, *0oC) MPa 0.4 0.5 0.5 0.6 Rated short-circuit breaking current kA *0 Rated short-circuit making current (peak) kA **0 Operating mechanism Spring Breaking times of rated short circuit current times Breaking time ms *0 Opening time ms *8***4 *4***2 Closing time ms **0 ± *0 **0*****0 CO time ms *5 *0 Rated operating cycle O*0.3s-CO***0s-CO
