FAQs
Install with the NF frame in mind, matching the three-pole configuration to the panel’s main bus arrangement. Since the unit ships without pre-wired connections, follow Eaton’s specification sheet for wiring diagrams and terminal assignments, mount securely on standard rails, and verify clearance for the 14 in depth, 20 in height, and 16 in width footprint to ensure proper fit and safe operation.
The NY123FABNSFNNC is a three-pole NRX cassette rated at 1200 A, designed for NF frame installations. It is UL Listed and intended for low voltage protection. Dimensions are 14 in depth, 20 in height, and 16 in width, with an approximate weight of 40 lb, supporting robust high-current distribution while maintaining manageable form factor.
Yes. With a 1200 A amperage rating and three-pole configuration, the NY123FABNSFNNC is designed to protect large feeders and main distribution paths in manufacturing and process environments. Its NRX series design provides reliable overload and short-circuit protection while integrating into OEM panel builds or retrofit switchgear with NF framing.
This NRX cassette is UL Listed, indicating compliance with recognized safety standards for electrical protection devices. The catalog notes also reference NRX NF UL Cass configurations and a 3P, 1200A setup, which supports conformity in panels requiring UL-listed low voltage protection and certified component assemblies within industrial systems.
The no pre-wired configuration reduces field wiring complexity, which can shorten installation time and labor costs during commissioning. The 1-year warranty provides supplier-backed protection, improving procurement risk management. Together, these factors contribute to lower downtime risk and predictable maintenance planning in high-current protection installations.
