1. Product Description
        ZW32-12 / M series of permanent high-voltage vacuum circuit breaker set microprocessor technology, modern network communication technology and new manufacturing technology in one switch. It is designed to meet the needs of distribution automation and designed to achieve a variety of measurement, protection and control functions.
        Compared with traditional electric device which has the following characteristics:
         1. Good performance, high reliability
         2. Hardware-based software
         3. with online monitoring and self-diagnosis function
         4. adapt to harsh environments, can -40C ~ + 40C safe and
     reliable operation within the ambient temperature range.
         The controller has a powerful communications processing functions: RS-232 interface local parameter setting and programming; optional GPRS, Modem and optical fiber Ethernet networking systems and remote data transmission capabilities.
         Product fully sealed design: In addition to the epoxy bearing shell outside, not in the auxiliary insulating material; sleeve mounted vertically, the output and input terminals are arranged transversely, even if connected to overhead lines, but also conducive to the cable access; integrally molded sleeve tube, ensure good air tightness.
         Can be equipped with isolation switch, with a clear break point, maintenance convenient and safe.
