Eaton EAFR-101S Arc Flash Relay - UL Recognized
Part Number: EAFR-101S
Quick Summary
The Eaton arc flash relay EAFR-101S provides fast, selective protection for panel and switchgear applications. Many plants struggle with nuisance trips and complex wiring that slow downtime recovery. UL Recognized and cUL Recognized certifications help meet North American safety standards, while the panel-mount design simplifies installation in existing enclosures. With support for 12 point sensors and 4 trip relays, it scales from small panels to multi-zone protection, delivering reliable protection and predictable maintenance costs. This translates to quicker fault isolation, reduced exposure, and easier compliance documentation for audits. Customers deploying this device can expect lower total cost of ownership through fewer false trips and simpler maintenance.

The EAFR-101S supports up to 12 point sensors and four trip relays, enabling selective tripping across multiple zones. This capability delivers targeted fault isolation, reduces downtime, and minimizes the scope of interruptions in complex switchgear and multi-line panels. Power range flexibility—130-240 Vdc and 125-250 Vac at 50/60 Hz—allows seamless integration across mixed plant electrical systems, reducing wiring changes during upgrades and enabling cross-site deployments. Light sensing inputs provide rapid arc detection, simplifying wiring and improving response times, which translates into safer operations and faster reset after a fault event. The panel-mount form factor, compact footprint, and a four-relay architecture support scalable protection schemes without requiring additional hardware. UL Recognized and cUL Recognized certifications reinforce compliance, while the 1-year (or 18-month from shipment) warranty offers predictable support. These attributes collectively improve efficiency, safety, and total cost of ownership in modern automation environments.
