Eaton / Cutler-Hammer FDPW367B – 800A, 3-Pole Vertical Bottom Feed Main Fusible Panel-Mount Switch – FDPW Series

Meet the Eaton / Cutler-Hammer FDPW367B, an industrial-duty main fusible panel-mount switch engineered for dependable load isolation and precise overcurrent protection in demanding power-distribution environments. With an 800A rating in a 3-pole configuration, this unit serves as the robust central disconnect in switchboards and panelboards, and its vertical bottom feed design is optimized for clean, efficient wiring and streamlined panel layouts.

Why professionals choose the FDPW367B

• High-capacity, three-phase protection: 800A capacity across a 3-pole setup ensures reliable handling of large three-phase loads and clean fault isolation during maintenance.
• Vertical bottom feed installation: Bottom-entry wiring supports neater cable routing, easier conduit connections, and tighter panel space utilization.
• Main fusible architecture: Centralized load isolation with overcurrent protection safeguards upstream equipment and downstream feeders from faults.
• Panel-mount convenience: Compact, integrated mounting within control panels reduces installation time and maximizes enclosure real estate.
• FDPW Series compatibility: Consistent performance and straightforward upgrades within Eaton’s protection family.

Ideal for real-world applications

This switch is tailor-made for switchboard and panelboard installations in manufacturing facilities, data centers, processing plants, and utility service panels where reliable main isolation and fusible protection are non-negotiable. Use it as the primary disconnect at the head of a distribution feeder or in retrofit projects that demand a rugged, fusible main switch integrated into a panel-mount footprint.

What you gain with the FDPW367B

• Enhanced safety through dependable isolation of critical loads during maintenance or fault conditions.
• Predictable protection for feeders and downstream equipment, reducing the risk of fault propagation.
• Streamlined panel manufacturing and easier future upgrades thanks to FDPW Series compatibility.
• Clear, device-specific performance for 800A service environments to support engineering decisions and project planning.

For installation and wiring, follow the FDPW Series guidelines to ensure proper fuse sizing, clearance, and mounting practices. The FDPW367B is designed to meet the needs of serious power distribution, delivering uptime and protection where it matters most.
