Eaton EAFR-08-35 Arc Flash Relay - UL Recognized
Part Number: EAFR-08-35
Quick Summary
Arc flash relay detects faults and triggers fast isolation in electrical panels and switchgear. This helps protect personnel and equipment from dangerous arc events. Operators often contend with nuisance trips or missed detections when sensors aren’t rugged or properly positioned in harsh environments. The EAFR-08-35 delivers UL Recognized and cUL Recognized safety certifications, a 35 m high-temperature glass fiber sensing loop, and a compact footprint that fits tightly packed electrical rooms. Its 8.46 in length, 7.87 in width, and 2.87 in height form a practical, lightweight solution for retrofit and new installations, enabling safer, more compliant protection across industrial facilities. The product integrates with Eaton protection systems to reduce commissioning time and improve overall system reliability.
