Fiber loop sensing with glass fiber enables long-range arc detection while preserving EMI immunity, reducing wiring complexity and installation time. This translates to faster fault isolation and lower commissioning costs, particularly in large switchgear or cabinet assemblies where space is at a premium. With 8000 Lux sensitivity, the sensor maintains discrimination in varied lighting, minimizing false trips and enhancing overall system reliability for critical manufacturing lines and data center environments. Certifications such as UL Recognized and cUL Recognized support regulatory compliance and streamline approvals for US and Canada-based projects, accelerating project timelines and reducing risk. The compact form factor (8.46 in x 7.87 in x 2.87 in) and light 0.25 lb weight simplify panel mounting and retrofits, delivering installation efficiency without compromising protection. A one-year warranty from installation (or 18 months from shipment) provides clear protection against early-life failures, improving total cost of ownership for OEMs and end users. Integrating this sensor with existing protection schemes reduces hardware diversity and simplifies maintenance, while the 50 m fiber loop length supports scalable coverage in modular switchgear and multi-rack cabinets.

FAQs
Install the EAFR-07-50 by locating it within the protected panel or cabinet, route the 50 m glass fiber loop along the area to be monitored, and connect to the corresponding arc flash relay interface per the Eaton specification sheet. Its compact 8.46 in length and 7.87 in width simplify mounting alongside other protection devices, while UL and cUL recognition help ensure seamless regulatory approval. The fiber loop minimizes additional wiring, and the sensor can be integrated into standard protection architectures without requiring major system rework.
Key specs include a 50 m fiber loop length using glass fiber, light sensing via a fiber optic medium, sensitivity rated at 8000 Lux, and a lightweight 0.25 lb sensor body. Catalog Number is EAFR-07-50, with product dimensions of 8.46 in (L), 2.87 in (H), and 7.87 in (W). Certifications include UL Recognized and cUL Recognized, supporting compliance across regions. These features collectively enable fast, reliable arc detection with minimal false trips in demanding environments.
Yes. The fiber loop sensor is designed for arc fault detection in switchgear, distribution panels, and cable tray enclosures, providing rapid arc detection along a 50 m loop. Its glass fiber sensing approach offers resilience in electrically noisy environments and supports large-area coverage with fewer physical sensors. This makes it particularly suitable for manufacturing lines and data centers where uptime and personnel safety are critical.
The EAFR-07-50 is UL Recognized and cUL Recognized, which confirms compliance with essential safety and performance standards for the US and Canada. These certifications simplify procurement and installation in multinational sites, reduce qualification cycles for end users, and support broader deployment in regulated industries such as food processing, energy, and critical facilities.
The product carries a one-year warranty from installation or eighteen months from shipment, whichever occurs first, reducing risk during initial operation. By lowering downtime through faster arc detection, minimizing nuisance trips, and reducing wiring requirements, the sensor can shorten payback periods and lower maintenance costs over the life of the protection system. Integration with existing Eaton protection schemes also simplifies ongoing support and spare part management.
