Eaton / Cutler-Hammer FDPBS364J – 200A, 3-Pole Branch Fusible Panel-Mount Switch – FDPBS Series

The Eaton / Cutler-Hammer FDPBS364J is a 200A, 3-pole branch fusible panel-mount switch engineered for industrial-duty performance in switchboards and panelboards. As a core component of the FDPBS Series, it delivers reliable load isolation and overcurrent protection, helping facilities keep critical electrical systems safe, accessible for maintenance, and ready for quick resets after faults.

Key advantages of the FDPBS364J

• 200 Ampere capacity across a three-phase (3-pole) configuration for demanding 3‑phase feeders
• Panel-mount design that integrates cleanly into standard switchboards and panelboards
• Branch fusible protection provides fast, dependable disconnection of downstream circuits
• Industrial-duty construction built to withstand harsh environments and continuous service
• Part of the FDPBS Series, ensuring consistent form factor and installation practices with other FDPBS components

Why this matters

In complex electrical systems, a clear and reliable isolation point is essential for safety and uptime. The FDPBS364J acts as a robust disconnect for three-phase loads, enabling safe maintenance, facilitating fault isolation, and protecting downstream equipment and wiring from overcurrent conditions. Its panel-mount integration supports organized, space-efficient protection within existing panel layouts.

Ideal for

• Industrial facilities and manufacturing environments needing dependable branch protection in switchboards and panelboards
• Electrical contractors performing installations, retrofits, or upgrades in commercial or light-industrial settings
• Maintenance teams requiring an accessible, reliable means to isolate 3-phase feeders for service or repair

Practical use scenarios

Use the FDPBS364J as a main or branch isolation point for 3-phase feeders, as a dedicated switch for motor circuits, or as a protective disconnect for critical downstream loads. Its fusible design provides the protective separation necessary to minimize fault propagation and simplify troubleshooting when issues arise.

Installation and best practices

• Install in panelboard or switchboard enclosures that accommodate 3-pole, 200A fusible switches
• Coordinate with compatible FDPBS Series components to maintain consistent mounting dimensions and wiring layouts
• Label clearly to indicate disconnect points and maintenance procedures for rapid, safe servicing
