Reyrolle 7XG35 ReyArc High Speed Arc protection

Why Reyrolle 7XG35

Arc flash incidents threaten people and equipment. Traditional protection can be too slow, causing hazards, damage, and outages. The Reyrolle 7XG35 ReyArc uses ultra-fast dual‑criteria detection for rapid, reliable response, improving safety and reducing operational risk.

High speed Arc Protection: Tripping Signal within 2ms

The 7XG35 is used in conjunction with P1X optical sensors to provide arc fault protection for MV or LV air insulated switchgear.

Direct and reflected light produced by arcing faults is detected. High speed protection operating time of 2 – 7ms.

The P1X sensors are connected to the 7XG35 device via fiber optic cables.

Integral self-supervision functionality monitors the 7XG35 device, the optical arc sensors and the fiber-optic connecting cables.

Optional overcurrent check functionality can be used to provide secure 2-out-of 2 tripping criteria.
