Eaton NRX low voltage cassette NG164FAB3SFNNC - IEC60947-2
Part Number: NG164FAB3SFNNC
Quick Summary
The Eaton NRX low voltage circuit breaker cassette protects high‑current switchgear in OEM and panel‑build applications. Engineers often struggle to fit 4P protection at 1600 A into large assemblies while maintaining fast commissioning and reliable operation. This IEC 60947-2 certified solution is NF IEC Cass compatible, simplifying safe integration into NF panels and standardizing safety practices. Its compact 14 in depth with a 20 by 21 in footprint helps fit large protections in space‑constrained enclosures, reducing panel complexity. Beyond compliance, the cassette delivers predictable maintenance costs, easier spare‑parts planning, and improved uptime for critical loads.

FAQs
The NG164FAB3SFNNC is engineered for NF frame panels and NRX assemblies, featuring a four-pole design rated at 1600 A. Its cassette form factor facilitates straightforward integration into existing NF switchgear, with consistent mounting interfaces and alignment to IEC 60947-2. Ensure enclosure space allows the 14 in depth and 21 in width footprint for a trouble‑free retrofit.
The unit is IEC 60947-2 certified, aligning with global standards for low‑voltage circuit breakers. It also offers NF IEC Cass compatibility for safe integration into NF panel builds and OEM configurations. This combination supports regulatory compliance, safer maintenance practices, and streamlined documentation for audits.
Applications with high-current distribution and space‑constrained enclosures benefit most, including data centers, manufacturing lines, and large industrial control panels. The four-pole design provides balanced protection across phases, enhancing fault clearance performance and reducing the likelihood of uneven loading that can trip ancillary equipment.
Take advantage of the no pre‑wired configuration to reduce field wiring time, while verifying compatible mounting dimensions (14 in depth; 20 by 21 in footprint). Pre‑planning with OEM documentation and the IEC 60947-2 specification sheet helps ensure a smooth swap or retrofit with minimal commissioning delays.
The 1‑year warranty, modular NRX cassette design, and IEC 60947-2 compliance contribute to lower lifecycle costs by simplifying spares planning, reducing downtime, and speeding maintenance cycles. For high‑reliability environments, this translates to improved uptime, predictable service intervals, and safer, standardized protection across panels.
