Product Description
1. PRODUCT OVERVIEWIntroducing the FRZW32 Series, an outdoor high-voltage vacuum circuit breaker that exemplifies excellence through its uniquely designed integrated solid-sealed pole and highly reliable operating mechanism. This state-of-the-art device is primarily employed in medium-voltage overhead power lines and masterfully handles switching, connecting load currents, overload currents, and short-circuit currents, ensuring seamless power management. Perfectly suited for substations, industrial and mining enterprises' power distribution systems, and rural power grids requiring frequent operations, this device offers unparalleled protection and control.
♦ Unparalleled reliability ensuring consistent performance
♦ Enjoy a completely maintenance-free experience throughout its entire operational lifespan
♦ Boasts a high mechanical and electrical lifespan, ensuring longevity
♦ Its compact and lightweight design facilitates quick and easy installation, saving time and effort.2. USAGE CONDITIONS
♦ This product operates optimally in an ambient air temperature ranging from -30ºC to +60ºC;
♦ Ensures reliable performance at altitudes not exceeding 3000 meters;
♦ Can withstand wind speeds not surpassing 34m/s;
♦ Designed to ignore vibrations or seismic activities from external switch and control devices;
♦ Handles pollution levels with a robust Grade IV rating;
♦ Efficiently stored within temperature ranges of -40ºC to +85ºC3. PRODUCT FEATURE♦ Revolutionary intelligent control function: Beyond local switch status control, this circuit breaker features three-stage overcurrent protection and automatic reclosing. With an RS-485 communication interface, it offers remote telemetry, adjustment, control, and signaling functions, making it ideal for automated distribution systems of various scales.
♦ Cutting-edge permanent magnet operating mechanism: This circuit breaker utilizes the latest permanent magnet operating mechanism, eliminating component wear. With a mechanical life reaching 3000 cycles-three times that of traditional spring mechanisms-a reduction of mechanical parts by 70% enhances switch reliability significantly.
♦ Innovative fully sealed structure design: This circuit breaker houses its vacuum arc-extinguishing chamber, operating mechanism, and linkage within a fully sealed base to prevent condensation and rust. This design allows for up to 10 years of maintenance-free operation.
♦ Ingenious compact structure: Featuring a new composite solid insulation material that integrates the vacuum arc-extinguishing chamber, main conductive circuit, and insulation support into an integrated sealed pole. This design resolves the miniaturization challenge while meeting external insulation requirements, resulting in a compact, advanced, and rust-free product.4. PARAMETERS
