Eaton Specification Sheet - FNJ1P18
Selling Policy 25-000 - Distribution and Control Products and Services
Feature: the FNJ1P18 employs an 18-inch wide unit size with a 22-inch depth and a 25-inch overall footprint to deliver a compact yet robust MCC module. This design reduces the required panel width, simplifies cable routing, and frees valuable space for auxiliary devices or future feeders without compromising access to the bus and breaker compartments. For panel shops, the streamlined enclosure supports faster assembly and more predictable lead times. Feature: 175 A trip rating and HJD circuit breakers deliver precise overload protection and short-circuit response. The arrangement enables current coordination with upstream protections and improves motor protection for high‑duty loads like conveyors and pumps. In practical terms, this means lower nuisance trips during startup, improved uptime, and clearer fault diagnostics during maintenance and testing in automated lines. Feature: J-frame feeder and handle-operated access simplify wiring and manual control. The feeder layout reduces wiring lengths, supports clean cable management, and enables quick removal for service. The handle mechanism provides intuitive, lockable access, enhancing safety during maintenance and minimizing the risk of unintentional operation in busy control rooms and repair bays. Feature: UL Listed certification confirms structural safety and electrical compliance, while the FNJ1P18 sits within Eaton's 9800 series ecosystem for consistent parts, spares, and service. Compatibility with J-frame feeder configurations, standard bus structures, and common MCC components helps ensure smooth procurement, easier stocking, and faster project turnover for industrial OEMs and electrical contractors. Feature: Warranty and service options under Eaton policy SP25-000 provide clarity on coverage—one year from installation or 18 months from shipment, whichever occurs first. This predictable support framework reduces lifecycle risk and supports maintenance budgeting. Combined with Eaton's distributor network and downloadable specification sheets, customers can plan preventive maintenance, swap-out strategies, and spare-part planning with confidence.

FAQs
FNJ1P18 is designed for 18-inch wide MCC installations with a 22-inch depth and a 25-inch footprint. When integrating into an existing panel, verify compatible cutouts and bus spacing, ensure adequate service clearance, and route J-frame feeder wiring cleanly from the bus to the HJD breakers. Refer to Eaton's specification sheet for exact mounting guidelines.
With a 175 A trip rating and HJD circuit breakers, FNJ1P18 provides robust overload protection and fast fault interruption, improving coordination with upstream devices. This reduces motor stress during startup and under fault conditions, supports safe energy management in automated lines, and helps meet motor protection standards for conveyors, pumps, and process equipment in industrial facilities.
Yes, FNJ1P18 is UL Listed, confirming electrical safety and compliance for standard industrial environments. The Eaton 9800 motor control center line is designed to integrate the HJD breaker framework and J-frame feeders within a compliant safety system, simplifying procurement and on-site commissioning for panel builders and end users who rely on established electrical standards.
FNJ1P18 is well suited for industries such as manufacturing, packaging, material handling, and process automation where compact MCCs support multiple motor feeders in limited spaces. It is particularly beneficial for machines with frequent startup sequences, conveyors, pumps, and HVAC equipment, enabling simplified wiring, faster panel assembly, and improved serviceability in OEM builds and maintenance shops.
Warranty coverage follows Eaton policy SP25-000: one year from installation or eighteen months from shipment, whichever occurs first. This provides predictable post‑sales support, with access to Eaton's documentation and distributor networks for parts, replacement breakers, and service programs. For ongoing maintenance, customers can plan preventive checks and authorized repairs to minimize downtime and extend MCC performance life.
