Description

The ZW20A-12C type AC High Voltage Vacuum Circuit Breaker is designed specifically for tri-phase electric systems operating at 50Hz with a rated voltage of 12kV. This advanced automatic controller is capable of breaking and closing load current, overload current, and short circuit fault current, serving as an essential device for controlling and protecting electrical networks.

This intelligent device integrates a sectionalizer, enabling distribution automation without the need for an additional control system. It features a sophisticated circuit breaker mechanism, allowing for regular opening and closing as well as auto reclosing capabilities that help isolate fault circuits during short circuit occurrences. Non-fault lines can quickly resume power supply, minimizing service interruptions and enhancing both social and economic benefits.

The ZW20A-12 is practical, reliable, and packed with multiple functionalities. Utilizing a microprocessor, the digital panel facilitates easy interaction, allowing for parameter adjustments. Additionally, the innovative GPRS communication system enables remote operations and teledata communication via mobile devices, transmitting line parameters and the running state of the equipment.

Constructed with a vacuum interrupter for arc extinguishing and SF6 gas for isolation, the circuit breaker is housed within a gas-sealed structure that prevents gas leakage. This design ensures enhanced operation reliability compared to traditional spring mechanisms, while the sealed main circuit offers anti-explosion, anti-condensation, and anti-dirt protection—making it the ideal choice for intelligent electrical network control and protection.
