Eaton PRW3-MCB-400A-600V - 400A, 600V, 3-Pole Breaker Busplug | AmpState

The Eaton PRW3-MCB-400A-600V is a purpose-built 3-pole breaker busplug designed for the Pow-R-Way III power distribution family. With a robust 400A amp rating and compatibility up to 600V, this busplug delivers focused protection for high-demand feeders and critical circuits in industrial environments.

Key advantages

• High-current protection in a plug‑in format: 400A capacity tailored for demanding loads without compromising installation flexibility.
• Three-pole design for balanced, three-phase protection: Ideal for standard 3-phase power systems common in manufacturing, processing, and heavy equipment environments.
• Seamless integration with Pow-R-Way III: Engineered to slot into the Pow-R-Way III bus system, enabling quick expansion and clean, modular distribution.
• Space-efficient configuration: Adds critical protection points without expanding the footprint of your switchgear or panel setup.

Practical use cases

• Expanding a Pow-R-Way III distribution scheme to add a dedicated 400A protection point for a high‑demand feeder.
• Retrofit scenarios where a new 3‑phase load needs reliable, plug‑in protection within an existing busbar network.
• Industrial environments requiring scalable, modular protection for large motors, presses, conveyors, or other heavy equipment.

Why this matters

The PRW3-MCB-400A-600V simplifies power distribution planning by offering a ready-to-install, high-capacity breaker busplug that aligns with Eaton’s Pow-R-Way III architecture. By enabling targeted protection at the point of use, it helps reduce wiring complexity, accelerates rollout of upgrades, and supports phased expansion as your facility’s electrical demand grows.
