Eaton 4FBAR NRX Phase Barrier - Four-pole Front Connect
Part Number: 4FBAR
Quick Summary
NRX phase barrier provides front-connect phase isolation for panel-mounted electrical protection in industrial control systems. The device helps prevent phase-to-phase faults and simplifies wiring during panel assembly, addressing common pain points around miswiring and lengthy commissioning. CE compliance and typical IP-rated enclosure expectations are standard considerations for such equipment, while safety-critical installations may reference SIL-related guidelines to fit risk assessments. The compact NRX 4FBAR supports fast installation, scalable four-pole configurations, and predictable maintenance costs for modern automation projects. By delivering reliable, space-efficient isolation, it enables cleaner panel layouts, easier troubleshooting, and faster project milestones across manufacturing lines and process control environments.

FAQs
The 4FBAR NRX phase barrier is a four-pole front-connect isolation device designed for panel-mounted electrical protection within the NRX family. It fits standard control panel architectures and small-to-mid sized enclosures. For procurement, use catalog number 4FBAR and UPC 786689647636 to ensure exact part matching and traceability during engineering approval and stocking.
Key specs include four-pole front-connect isolation and a very compact profile of 0.04 inches in length, height, and width, with a weight of 0.04 lb. The catalog number is 4FBAR and the UPC is 786689647636, enabling precise identification in drawings and BOMs for reliable installation in electrical protection circuits.
Yes. The NRX phase barrier is designed for panel-level phase isolation and is well suited for motor control centers and other electrical protection circuits. Its four-pole design supports multi-phase schemes, while its front-connect construction simplifies wiring, reduces field installation time, and improves fault isolation in dynamic industrial environments.
CE compliance is commonly referenced for electrical protection devices like the NRX phase barrier, and many installations consider IP-rated enclosures and SIL-related guidelines as part of system safety assessments. Always verify that your installation meets IEC standards and local electrical codes, and consult Eaton documentation for any specific certification details relevant to your region and application.
The NRX 4FBAR reduces wiring errors and commissioning time thanks to a straightforward front-connect design, translating to faster project readiness and fewer in-field faults. The compact form factor saves cabinet space, enabling tighter control panels and lower enclosure costs, while reliable phase isolation improves uptime and lowers total cost of ownership over the system lifecycle.
