Draw out Type 12kv 630A Vacuum Circuit Breaker with Insulated Cylinder

VS1 (ZN63A) -12(24)M sequence indoor high voltage vacuum circuit breaker is geared up with Modular system, which has a far more secure integrated performance. This VCB is utilized for AC 12kV, 50Hz indoor high voltage switchgear, broadly relevant to electrical power stations, substations, and industrial and mining enterprises to manage or safety electrical power transmission and distribution systems, specifically for the critical high altitude breaking load and regular procedure area and reputable interlock function.
The VCB can be used for really recurrent operation area, equipped with KYN28A-12 handcart type swap cabinet, and the set variety VCB can also be used for XGN sequence switch cupboards. It conforms to Nationwide CZPT GB1984-2003, and the connected IEC requirements.
      The circuit breaker is created as a entrance-rear split charging composition, which the two can be utilised as a fixed installation unit, and also be equipped with the chassis as employed in the mounted, handcart device.
