Eaton / Cutler-Hammer FDPW365TR – 400A, 3-Pole Vertical Top Feed Main Fusible Panel-Mount Switch – FDPW Series

The Eaton / Cutler-Hammer FDPW365TR is a rugged 400A, 3-pole vertical top-feed main fusible panel-mount switch from the FDPW Series. Engineered for industrial environments, it delivers trusted load isolation and dependable overcurrent protection where it matters most in switchboard and panelboard installations.

Why this FDPW365TR stands out

• High-current, three-pole protection provides a single, centralized disconnect for large feeders and motor circuits, with built-in fusible protection that simplifies safety and coordination.
• Vertical top-feed configuration streamlines wiring and panel layout, allowing clean, efficient cable routing from the top and minimizing cabinet rearrangements.
• Panel-mount design facilitates straightforward integration into standard industrial panels, reducing installation time and easing fuse replacement and routine maintenance.
• Industrial-duty reliability built to withstand demanding environments, offering steady switching performance and clear, visible isolation when opened.
• FDPW Series compatibility ensures easy cross-reference with other FDPW devices, enabling scalable protection schemes across your distribution panels.

Ideal use cases

• Main disconnects in distribution panels where a robust fusible switch is required to safely isolate the entire load during maintenance or fault conditions.
• Protection point in panelboards for large electrical feeders and critical process lines in manufacturing, processing, or facilities with high startup surges.
• Service-entry or retrofit applications needing a credible, code-compliant isolation device that’s readily available and easy to source.

What makes it practical in the real world

• Eliminates the need for separate fuse holders by integrating fusing directly into the panel-mount switch, reducing wiring complexity and potential fault points.
• Top-feed design reduces cable clutter and simplifies future upgrades or wiring changes within crowded electrical rooms.
• Backed by Eaton’s decades of electrical safety and protection expertise, offering confidence in parts availability, service support, and seamless compatibility with the FDPW ecosystem.

Pro tips for deployment

• Ensure front-access fuse replacement readiness; the panel-mount form factor is designed for convenient maintenance without disturbing downstream circuitry.
• Check enclosure space and busbar alignment to support the vertical top-feed orientation and maximize safe operation.
• Coordinate with compatible FDPW fuses and accessories to build a cohesive protection strategy that aligns with your system’s protection coordination goals.

Engineered for facilities that demand reliable isolation and robust protection, the FDPW365TR is a purpose-built solution for high-current panelboard applications. Choose this main fusible panel-mount switch when you need a proven, easy-to-service disconnect that integrates smoothly with Eaton’s FDPW protection family.
