Product Details

China VS1 (ZN63A) -12/24 Model indoor AC high voltage vacuum circuit breaker is a type of holistic and completely sealed HV switchgear, it has compactable dimension and small volume. The VCB applies to power system of rated voltage 12kV and 24kV, three-phase and AC 50/60Hz. It is applicable in occasions with frequent operations, acting to protect and control line and electric apparatus. 

Product features

  1. Conform toconforms to IEC62271, GB1984, JB3855 and DL1403 standard
  2. Ideal contact material and shape, ensuring low current carrying value and stable contact resistance
  3. Integrated design of main conductive circuit made of compound isolation material and operating mechanism
  4. Few components and parts, compact and logical structure, assuring more reliable and safer operation
  5. Compact design enables the breaker to be installed within almost all switchgears
  6. Epoxy resin insulation cylinder can withstand severe environmental impacts, enabling VS1 breakers to be used in all kinds of situations.
  7. Superior cost performance, ideal choice for engineering programs
