FAQs
Yes. The RFMI2F is designed for the NRX frame with RF mounting and fixed breakers. It uses a two-way fixed mounting method compatible with the RF frame and aligns with the interlock accessory kit to ensure secure operation and straightforward retrofit. Confirm frame type and breaker rating before installation to ensure optimal performance.
The RFMI2F carries UL Listed and ANSI CSA Certified marks and is NEMA Compliant. These certifications validate safety, electrical performance, and regulatory adherence, reducing audit findings and easing procurement for regulated facilities such as data centers, manufacturing lines, and safety-critical MCCs.
By mechanically interlocking the breaker with the door or access point, the RFMI2F prevents accidental reclosure during maintenance, enhancing personnel safety. The reliability of the latch action minimizes misoperation events, which translates to reduced maintenance downtime and fewer troubleshooting cycles in MCCs.
Two-way fixed mounting allows straightforward orientation in available NRX RF frames and supports simple field adjustments during retrofits. Ensure clearances around the interlock, verify frame compatibility, and maintain proper alignment with the fixed contact geometry to avoid binding or misalignment.
The RFMI2F includes a one-year factory warranty from shipment date, with Eaton support for corrective actions. Expected ROI comes from improved safety, reduced unplanned downtime, and simplified spares/maintenance, particularly in facilities with frequent maintenance cycles and strict regulatory requirements.
