High Voltage Vacuum Circuit Breaker (HV VCB)

ZN85 35KV Indoor Cart-Type High-Voltage Vacuum Circuit Breaker

The VXC1-12 series indoor trolley-mounted high-voltage vacuum circuit breaker is a three-phase AC 50Hz, 12kV rated indoor switchgear. It is suitable for control and protection in industrial and mining enterprises, power plants, substations, and electrical facilities, and is ideal for frequent operation. The operating mechanism is integrated with the circuit breaker body, allowing it to be used as a fixed installation unit or as a trolley unit with a dedicated propulsion mechanism. The main circuit utilizes an integrally sealed column, resulting in a compact, highly reliable, and maintenance-free circuit breaker. It is compatible with center-mounted trolley-mounted switchgear such as the KYN28A-12 (GZS), and can also be used with XGN series fixed switchgear in fixed configuration.

Normal Operating Environment
Ambient temperature: not exceeding 40°C, not below -10°C (storage and transportation at -30°C permitted).
