RPZ8-12M High-Voltage Permanent Magnet Miniature Vacuum Circuit Breaker
RPZ8-12M High-Voltage Permanent Magnet Miniature Vacuum Circuit Breaker
Product Description
The RPZ8- 12M 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 high- voltage prepaid metering
switching, 10 kV 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.
