VK12-E-12P Vacuum circuit breaker with fixed pole

VK12-E-12P Series fixed pole vacuum circuit breaker is equipped with special vacuum interrupter with low loop resistance. Its contact has low electric wear speed, long electrical life, high fracture withstand voltage level, stable dielectric insulation strength, rapid recovery after arc, low current cut-off value and strong breaking capacity.

The operating mechanism adopts spring energy storage structure, with manual and electric energy storage functions. The operating mechanism is located in the frame behind the arc chamber. The product has the characteristics of long life, less maintenance,and low noise.
