Entec's Three-Phase SF6 Gas Automatic Circuit Reclosers(EVR-1, EVR-2, EVR-3) are designed for the application in overhead lines and substations for voltage classes up to 15.5kV, 27kV, and 38kV.

The operating mechanism uses a permanent magnetic actuator that guarantees maintenance-free operation. The vacuum interrupters for arc quenching ensure high reliability.

The bushings are made of epoxy with silicone rubber housing. The Recloser tank and control cubicle are made of stainless steel, which have strong endurance against hot, humid, dusty, or corrosive environment.

The Recloser is supplied with complete microprocessor-based controller(ETR300-R or EVRC2A-NT) including metering, monitoring, recording, and communication functions.

The Recloser has been fully type tested by accredited laboratories such as KEMA, CESI or KERI according to the international standards ANSI C37.60 and IEEE 62271-111.
