ZW43-12M Permanent magnet vacuum circuit breakerDetailed product description：

ZW43-12 (permanent magnet) vacuum circuit breaker has applied multiple patented technologies, making it have 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.

Product features and reference standards
ZW43-12 (permanent magnet) vacuum circuit breaker is designed specifically to meet the needs of distribution network automation, and can achieve various measurement, protection, and control functions. Product fully sealed structural design; There are no additional insulation materials inside the shell except for the epoxy support; 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 integral molding sleeve can ensure good air tightness. At 630A, the load shedding operation exceeded 30000 times, resulting in less maintenance workload. Cut off the rated short-circuit current of 20kA for more than 30 times. Configurable isolation knife switch, with obvious disconnection points, easy to maintain and safe.
