DESIGN

Boerstn 33KV three phase class III recloser is in accordance with the standard ANSI/IEEE C37.60.

The recloser is designed to provide self-contained 33KV circuit protection with series trip,solenoid operation and electronic control single break contact structure and fault interruption under vacuum. The vacuum interrupters are in accordance with ANSI/IEEE C37.85.  The recloser is accordance with ANSI/IEEE C37.85. 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.
