Product Description
1. PRODUCT OVERVIEW
The FRZW32 Series outdoor high-voltage vacuum circuit breaker adopts a uniquely designed integrated solid-sealed pole and a highly reliable operating mechanism. This device is mainly used in medium-voltage overhead power lines for the purpose of switching, connecting load currents, overload currents, and short-circuit currents. Suitable for use in substations, industrial and mining enterprises' power distribution systems, as well as rural power grids that require frequent operation, for protection and control purposes.
♦ Extremely high reliability
♦ Completely maintenance-free throughout its entire lifespan
♦ High mechanical and electrical lifespan
♦ Compact size and lightweight, facilitating installation. 
2. USAGE CONDITIONS
♦ Ambient air temperature: -30ºC to +60ºC;
♦ Altitude: not exceeding 3000 meters;
♦ Wind speed not exceeding 34m/s;
♦ Vibrations or seismic activity from external switch and control devices can be ignored;
♦ Pollution level: Grade IV;
♦ Storage temperature: -40ºC to +85ºC
3. PRODUCT FEATURE
♦ Intelligent control function: In addition to on-site switch status control, three-stage overcurrent protection, and automatic reclosing, this circuit breaker also has an RS-485 communication interface that enables remote telemetry, remote adjustment, remote control, and remote signaling functions. It is suitable for various scales of automated distribution systems.
♦ Permanent magnet operating mechanism: This circuit breaker adopts the most advanced permanent magnet operating mechanism, with zero wear on its components. The mechanical life of the mechanism can reach 3000 times, which is three times that of ordinary spring mechanisms. Due to the reduction of mechanical parts by 70% compared to spring mechanisms, the reliability of the switch is greatly improved.
♦ Fully sealed structure design: The vacuum arc-extinguishing chamber, operating mechanism, and operating linkage of this circuit breaker are fully sealed inside the base, solving the problem of condensation causing rust on the circuit breaker parts. The product can achieve maintenance-free operation for up to 10 years.
♦ Compact structure: This circuit breaker adopts a new type of composite solid insulation material, which integrates the vacuum arc-extinguishing chamber, main conductive circuit, and insulation support into an integrated sealed pole, completely solving the contradiction between miniaturization of the vacuum arc-extinguishing chamber and meeting external insulation requirements. The entire product is designed with advanced and reasonable structure, compact size, no condensation inside, and no rust on the mechanism.
