GENERAL FEATURES

The SF6 gas insulated vacuum recloser is an electronic automatic circuit recloser designed for the highest mechanical and electrical reliability.
The unique design of auto recloser meets the latest technology with the combination of vacuum interruption, bi-stable magnetic actuator sealed in a stainless steel tank with SF6 gas as the insulation medium and microprocessor based control.
This means completely oil free, environment free design and no hazardous products are produced during the interruption.
Especially, the mechanism is operated by a bi-stable magnetic actuator which requires a minimum power consumption for operation with battery sources only.

This feature independent from extenal power sources provides the recloser with dead line operation capability for many SCADA applications and ring systems.
The microprocessor based electronic recloser offers superior co-ordination and application capability meeting IEC 255-3 electrical relays and kyle electronic recloser curves and esigned in accordance with ANSI / IEEE C37.60 and manufactured under a quality system conforming to ISO 9001.
