Fusional Pole-Mounted Circuit Breaker (ZW20)
The Fusional pole-mounted circuit breakeruses uses vacuumarc extinguishing and SF6 gas as the insulating medium. It is designed for breaking and making load currents, overload currents, and short-circuit currents.
- Overview
- Recommended Products
1、High protection level
Fully sealed and fully insulated design with IP65 protectionlevel,meeting anti-condensation requirements. All aviation conrhectors are military-grade components, providing an exceptionally high level of protection.
2. high fault detection accuracy
Equipped with voltage and current transformers (sensors) andan energy metering module, it calculates active power, reactive poweer power factor, frequency, and energy. By utilizing a multi-criteria fusicon algorithm, it enables rapid fault detection and isolation, ensurirng the safety of the 10kV power line.
