FAQs
Begin with de-energized equipment and confirm the panel supports NRX RF cassettes. Mount the cassette in the designated NRX frame, secure with standard mounting hardware, and connect field wiring per the catalog notes. Since this model uses no pre-wired connections, you’ll complete terminations at the panel bus and verify alignment with the 3P configuration before testing protective relays.
Yes, the RY303FABNSFNNC is designed for the RF frame within the NRX family. Ensure standard clearance around the cassette per the enclosure manufacturer’s guidelines and provide 18 inch depth plus the 24 by 24 inch footprint. Maintain access for maintenance and inspection, and follow UL-listed mounting practices to preserve performance and fault-clearing speed.
The RY303FABNSFNNC carries UL Listed certification, confirming compliance with recognized safety standards for low-voltage circuit protection. It is specified as a three-pole device with a 3000A amperage rating, part of the NRX Series RF family. The catalog notes emphasize no pre-wired installation, which supports consistent, code-aligned assembly in compliant switchgear.
This cassette is designed for industrial deployment with a compact footprint of 18 inches in depth and a 24 by 24 inch footprint, weighing about 60 pounds. Its three-pole RF frame supports robust three-phase protection even in demanding environments. For rugged settings, pair it with appropriate enclosures and provide adequate vibration and dust control per site requirements.
The device carries a 1-year warranty from Eaton, providing post-sale protection. Benefits that reduce TCO include a high 3000A rating, modular NRX cassette design for rapid swaps, and a no pre-wired installation that cuts labor time during commissioning. Together, these factors help minimize downtime and accelerate project completion while maintaining regulatory compliance.
