Overview
ZW32 series outdoor high-voltage vacuum circuit breakers are outdoor high-voltage distribution devices with rated voltage of 12KV-36KV and three-phase AC of 50Hz.It is mainly used for opening and closing the load current, overload current, short circuit current in power...
Product Details
Product Description
The recloser is designed to provide self-contained 24KV circuit protection with series trip,solenoid operation and electronic control single break contact structure and fault interruption under vacuum. The recloser is designed to sense line-to-ground, line-to-line or three-phase fault currents and interrupt all three phases of the distribution circuit simultaneously. The recloser is equipped with a electronic type ground feature. For fault target,Automatic Circuit recloser will be provided with an indicator for detection of fault current on individual phase or ground. If the Electronic Control cubicle of Reclosers or Recloser itself require an auxiliary transformer, the manufacturer must provide the same at his cost. The recloser is provided with in-built auxiliary transformer of required rating to provide power supply to the control panel.
