FAQs
The EAFR-101B is Eaton’s arc flash relay, a point sensor unit designed to protect electrical panels from arc flash events. It integrates up to 12 point sensors and four trip relays to detect arcing and initiate a safe interlock. Typical applications include switchgear panels in industrial automation and commercial power distribution, where fast, selective tripping is critical.
Yes. The device operates at 50/60 Hz and supports a wide voltage range including 80-265 Vac/dc and 120-240 Vdc power supply variants. It is designed for panel mounting in environments requiring reliable arc flash detection and interlocking with standard AC or DC control circuits.
It is UL Recognized and cUL Recognized, confirming compliance with safety standards for electrical protection devices. This certification, along with its panel-mount design and 50/60 Hz operation, provides confidence during audits and supports installation in regulated facilities.
With 12 point sensors, the EAFR-101B can monitor multiple locations and coordinate tripping via four relays, enabling zone-selective interlocking and faster isolation. This reduces arc flash energy exposure, minimizes downtime, and supports scalable protection schemes in larger switchgear assemblies and complex automation lines.
Maintenance is straightforward thanks to a panel-mounted design and Eaton’s warranty policy. Expect periodic checks of sensor integrity and interlock wiring. The ROI comes from improved safety, reduced incident costs, and potential compliance savings by meeting arc flash protection requirements and lowering risk in high-energy applications.
