VK12-E-12 Vacuum circuit breaker - with composite insulated pole



VK12-E-12 series composite insulated pole vacuum circuit breaker is equipped with a special vacuum arc extinguishing chamber with low loop resistance. Its contact has low electrical wear rate, long electrical life, high fracture withstand voltage level, stable dielectric insulation strength, rapid post arc recovery, low current cutoff value and strong breaking capacity.



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