ZW32-24 series column mounted vacuum circuit breakerDetailed product description：

ZW32M-24 (permanent magnet) vacuum circuit breaker is a combination series product: a combination isolation switch can be optionally selected to provide a visible break for line maintenance; The circuit breaker is equipped with a permanent magnet operating mechanism, which forms the best cooperation with the vacuum arc extinguishing chamber to complete the operation function, and the closing and opening actions are stable and reliable; The entire product design is advanced and reasonable, with a compact structure, a completely sealed box, no condensation inside, no rust on the components, and greatly improved switch reliability; By adopting a new composite solid insulation structure, the vacuum arc extinguishing chamber, main electrical circuit, insulation support, etc. are organically combined into an integrated solid sealed pole, completely solving the contradiction between miniaturization of the vacuum arc extinguishing chamber and meeting external insulation requirements; The casing is arranged horizontally, and the output and input ends are arranged horizontally, which is conducive to cable connection even when connected to overhead lines; The optional isolation switch is equipped with a manual operating mechanism, which forms a mechanical anti misoperation lock; The casing of the circuit breaker is available in two options: stainless steel and ordinary steel plate treated with Dacromet rust prevention, which can achieve a lifespan of 10 years without the need for paint maintenance; The power system within the intelligent control unit ensures at least 24 hours of continuous battery power supply in the event of system power failure, and can control the switch to perform reliable actions.

Due to the application of multiple patented technologies, ZW32M-24 (permanent magnet) vacuum circuit breaker has many advantages: no SF6, no oil, less environmental impact, and conducive to environmental protection; Small unit size, lightweight, and easy to install on columns; The intelligent control unit is compact and can be easily installed under the column. It can be equipped with a wireless remote control and can control the opening and closing of switches within a range of 100 meters; Suitable for on-site operation and remote control of urban and rural power grids; Except for replacing the battery every 5 years, the circuit breaker body is basically maintenance free for life.
