Eaton PRW3-FUS-400A-600V - 400A, 600V, 3-Pole Fusible Busplug | AmpState

The Eaton PRW3-FUS-400A-600V Fusible Busplug is a purpose-built protection device for Pow-R-Way III busway systems. Delivering a 400 A rating at 600 V across three poles, this fusible busplug provides fast, reliable overcurrent protection right at the source of your distribution feeders.

Built for modular, high-density power distribution, this three-pole fusible busplug integrates seamlessly with Pow-R-Way III layouts. It protects essential feeders and subfeeds without adding extra enclosures, helping you maintain a clean, scalable, and efficient electrical distribution footprint.

Key differentiators

• Three-pole protection tailored for three-phase systems—perfect for motors, drives, and multi-line feeders.
• 400 A, 600 V capability—designed for demanding industrial applications and higher protection levels.
• Fusible busplug form factor minimizes wiring complexity and space requirements within Pow-R-Way III installations.
• Modular, plug-in design supports rapid installation, simple maintenance, and scalable distribution as your facility evolves.

Ideal use cases

• Industrial facilities implementing modular Pow-R-Way III busways who need reliable feeders protection without adding bulky switchgear.
• New builds or retrofits where integrating protection directly at the busway node reduces wiring and simplifies maintenance.
• Data centers and large commercial environments seeking compact, centralized protection for critical feeder circuits.

How it helps: as a Fusible Busplug, the PRW3-FUS-400A-600V provides targeted overcurrent protection that isolates a protected feeder during faults, helping to minimize downtime and protect downstream equipment while keeping the rest of the busway energized for continued operation.
