Reyrolle 7XG35 ReyArc High Speed Arc protection

Why Reyrolle 7XG35

An arc flash occurs when electrical current deviates from its intended path, traveling through the air between conductors or to the ground, releasing intense heat, light, and a concussive pressure wave capable of causing severe damage

Arc flash is critically important as incidents threaten personnel and equipment which leads to operational downtime.

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

High speed Arc Protection: Tripping Signal within 2ms

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.
