Eaton EAFR-101DB Arc Flash Relay - UL/cUL Recognized
Part Number: EAFR-101DB
Quick Summary
Arc flash relay Eaton EAFR-101DB protects electrical panels by rapidly detecting arc events and tripping the circuit to prevent injury and equipment damage. Engineers often wrestle with nuisance trips or slow responses caused by transient faults or lighting surges, which erode uptime and safety margins. This model carries UL Recognized and cUL Recognized approvals, underscoring compliance for critical industrial environments. With a DIN-rail footprint and flexible power options, it fits compact panels and diverse plant voltages. The inclusion of 12 point sensors and four trip relays enables scalable protection schemes, while light-sensing inputs add automatic fault detection without extra wiring. Designed for reliability, the EAFR-101DB supports efficient maintenance, safer operations, and regulatory compliance across manufacturing and processing facilities.

FAQs
Install the EAFR-101DB directly onto a standard DIN rail in the control cabinet. Connect the four digital outputs to the relevant contactors or feeders and wire the 12 point sensors as indicated in the Eaton specification sheet. Ensure the unit is powered by the 120-240 Vdc or 125-250 Vac supply range and confirm proper termination for reliable tripping.
The device supports 80-265 Vac/dc as its voltage rating, with a frequency rating of 50/60 Hz. It accepts a power supply range of 120-240 Vdc and 125-250 Vac, enabling flexible use across mixed electrical environments common in industrial facilities.
Yes. The EAFR-101DB is designed for arc flash protection in control panels and electrical enclosures, with multiple sensors and relays to provide rapid fault detection and isolation. It is UL Recognized and cUL Recognized, supporting regulatory compliance in North American installations.
The EAFR-101DB carries UL Recognized and cUL Recognized certifications, which validate safety and performance for industrial equipment. These approvals simplify procurement, support compliance during audits, and reassure engineers that the relay meets established North American electrical safety standards.
Regular functional testing of arc flash sensing and trip outputs is advised, typically during preventive maintenance cycles. Inspect sensor health, verify wiring integrity, and perform periodic trip verification to ensure reliable operation. Routine testing reduces unplanned downtime and extends service life, delivering measurable ROI in safety-critical applications.
