The ZW43-12 series outdoor intelligent vacuum circuit breaker is primarily designed for use in 12kV, 50Hz three-phase AC distribution networks. Depending on specific configuration requirements, it can provide functions such as overcurrent protection, overcurrent delay protection, fast-breaking protection, and single-phase grounding protection (low-current grounding protection). It can be reliably connectedto FTU terminals, enabling remote control, telemetry, tele-signal, and tele-adjust functions. Utilizing transmission systems such as GSM, CDMA, GPRS, it allows online monitoring of equipment operational status, making the device more user-friendly. It is the preferred equipment for distribution network automation.
