The GYZ8-12M/口-口 High-Voltage Permanent Magnet Miniature Vacuum Circuit Breaker (hereinafter referred to as the circuit breaker) is characterized by its cost-effectiveness, frequent operations, and high lifespan. It is commonly used for 10kV highvoltage prepaid metering switching, 10kV reactive power compensation cabinet switching, and the opening/closing functions in compact cabinet sets. It can interrupt and close unloaded currents, load currents, and short-circuit currents within the specified range. After capacity reduction, it can also be used in capacitive load circuits.
