Advanced optical sensors
Our Reyrolle 7XG31 uses advanced optical sensors to detect arc faults. It monitors light flashes for rapid, millisecond detection. Clear faults quickly for improved safety and operational continuity.
Why Reyrolle 7XG31?
The Reyrolle 7XG31 arc protection system rapidly clears arcing faults. Protect busbars, metal-clad switchgear and associated cable boxes from damaging arc events with this modern solution.
Traditional current-based protection struggles with arcing faults, causing slow clearance times. These delays increase risks to personnel and can damage the plant. Siemen’s Reyrolle 7XG31 uses optical detection for fast, reliable clearance of arcing faults.
Key benefits
Enhance personnel safety
