ZW20-12F Series Outdoor High Voltage Vacuum Circuit Breaker (Watchdog)
● Product Information
ZW20-12F is an advanced product which improved based on two products: ZW20-12 pole circuit breaker and FZW28F-12 outdoor demarcation vacuum load switch, has manual and electric operation functions. Its switch body adopts Japan Toshiba VSP5-12 maintenance-free load switch, mature cold-rolled steel box-type sealing structure, which has good sealing performance. So that it is not affected by the external environment, is a maintenance-free product. The product uses Vacuum interruption and SF6 gas as insulating medium. The circuit breaker can be equipped with an intelligent controller, and its own PT is used as a power supply, which becomes an intelligent circuit breaker with voltage and current signal output and control, which is a good product for pole-mounted circuit breakers.

1.Flexible and convenient operation: the product can be both electric energy storage, electric switching, but also manual energy storage, manual switching function and can be operated remotely in close proximity.
2.Excellent breaking performance: breaking rated short-circuit current up to 30 times
3.Low operating power and high reliability: Newly designed miniaturized electric spring mechanism minimizes the number of components and the rated power of the energy storage motor (approx. 40 W).
4.Flexible installation: can be installed by hanging or sitting on the pole.
5.Maintenance-free characteristics: the secondary components of the main circuit of the circuit breaker and the actuator are sealed in SF6 gas (zero gauge pressure), which is not affected by the external environment, and has stable, reliable and maintenance-free performance.
6.Reliable sealing performance: adopting mature sealing structure technology, reliable sealing performance.
7.Excellent insulation performance of inlet and outlet wires: the use of silicone rubber sleeves, so that the insulation distance between the terminals is sufficient, and the external insulation performance is excellent.
8.Safe to use: Explosion-proof device is installed on the top of the box, even if an accidental internal failure occurs, there will be no high temperature gas or objects over 10mm leakage and escape.
9."four remote" functions：it can be used with intelligent controller to achieve remote control, telemetry, telecommunication and remote adjustment.
