ZW20-12F Outdoor HV Intelligent Sectionalizing Vacuum Circuit Breaker

Overview
The ZW20-12F Outdoor High-Voltage Intelligent Sectionalizing Vacuum Circuit Breaker is a high-voltage switchgear device with a rated voltage of 12 kV and operates on three-phase AC at 50 Hz. It is primarily used to interrupt and close load currents, overload currents, and short-circuit currents in power systems.
This breaker is suitable for substations, industrial and mining enterprises, and urban-rural distribution networks, serving as a protective and control device. It is especially ideal for locations with frequent operations and automated urban distribution networks. Paired with a controller, it meets the requirements for distribution automation systems and can reliably perform the traditional function of a recloser.
The device features a mature box-sealed structure filled with SF₆ gas, providing excellent sealing properties to shield it from environmental impact, making it a maintenance-free product. Its spring-operated mechanism utilizes a direct-action chain drive and multi-stage tripping system, offering high operational reliability, making it an ideal choice for pole-mounted circuit breakers.
