Westinghouse P3F321RGN - 30A, 120/208V, Fusible Bus Plug

Meet the Westinghouse P3F321RGN Fusible Bus Plug — a purpose-built solution for dependable power distribution in demanding environments. With a 30A rating and a 120/208V supply, this bus plug is engineered to slot directly into busway and panelboard systems, delivering protective fusing right at the point of distribution.

Key advantages that set this apart

• Precise electrical fit: 30A, 120/208V compatibility ensures it aligns with common commercial and light industrial electrical configurations, reducing custom fabrication for retrofits.
• Compact fusible protection: A dedicated bus plug that provides overcurrent protection exactly where you need it, helping to isolate faults and protect downstream equipment.
• Easy retrofits and upgrades: Specifically designed for maintenance, repair, and upgrade projects where compatible, hard-to-find busplugs are required to keep existing infrastructure viable.
• Industrial- and commercial-grade durability: Built to perform in busy facilities, process environments, and retrofit scenarios where continuous uptime is critical.
• Versatile deployment: Suitable for process equipment feed, service panels, and distribution nodes within busway networks, accommodating a range of configurations without invasive changes.

Ideal use cases

This fusible bus plug shines in environments where reliability and compatibility matter most. Use it for:

• Industrial plants upgrading power distribution without replacing entire busway sections
• Commercial facilities adding or relocating feeders within existing panelboards
• Retrofit projects where a known, compatible bus plug is required to maintain protection coordination
• Equipment feeds for critical process lines that demand predictable fuse behavior and quick isolation during faults

How this integrates into your system

The P3F321RGN is designed to integrate with standard busway and panelboard architectures, delivering a straightforward pathway for safe, organized overcurrent protection. By placing the fuse element at the distribution point, it helps streamline troubleshooting and minimizes disruption during maintenance windows. This makes it a practical, long-term addition for facilities aiming to preserve existing infrastructure while enhancing protection reliability.

Practical considerations and tips

• Confirm compatibility with your current busway and panelboard model before acquisition to ensure proper fit and coordination
• Plan for routine inspection of fusible elements and housing integrity as part of your preventive maintenance schedule
• Coordinate with your electrical team to align fuse ratings and protective devices across the distribution network for cohesive protection

For facilities seeking a dependable, field-ready solution that pairs Westinghouse reliability with targeted protection at the distribution level, the Westinghouse P3F321RGN Fusible Bus Plug delivers the precise, maintainable option your power system needs.
