Rated Voltage
a. Nominal system voltage-30,000volt
b. Rated maximum voltage -40500 volts.
c. Power frequency withstand voltage-70 KV
Rated frequency - 50 Hertz
a tolerance of ± 5 percent. Rated symmetrical making current is the same value as the
rated symmetrical interrupting current, with asymmetrical
relationships as defined in ANSI/IEEE C37.60.
Rated  Impulse Withstand Voltage - 170 KV.

36KV three phase class III recloser is in accordance with the standard ANSI/IEEE C37.60.
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 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

How to wire with vacuum switch

Make sure the end –user follow below diagram to connect the junction box to BRZW32 vacuum switch. Junction box is self-power supply controller

Before employ switch for H.V.line, please make sure each cable connector is correct connection.

Please push each A.B.C phase switch button to check if connection in good condition. The proper work is each phase electric control is corresponding correct phase switch.
