Eaton / Cutler-Hammer FDPWS364J – 200A, 3-Pole Branch Fusible Panel-Mount Switch – FDPWS Series

Introducing the Eaton / Cutler-Hammer FDPWS364J — a 200A, 3-Pole Branch Fusible Panel-Mount Switch from the FDPWS Series. Engineered for industrial-duty conditions, this device delivers reliable load isolation and overcurrent protection right where it’s needed in switchboards and panelboards.

Why the FDPWS364J stands out

• Three-phase, 200A performance designed to handle demanding commercial and industrial circuits with balanced protection across all phases.
• Panel-mount efficiency provides a compact, space-saving solution that integrates neatly into existing enclosures without sacrificing accessibility or operability.
• Dedicated branch fusible protection combines isolation with overcurrent protection in a single, reliable assembly—reducing wiring complexity and simplifying panel design.
• Rugged, industrial-duty construction built to stand up to operational environments where uptime matters and fault events require swift disengagement.
• Clear load isolation ensures safe maintenance and reduces the risk of unintended energization across the protected circuit.

Ideal applications

• Switchboards and panelboards in manufacturing facilities, plants, and other industrial settings
• Three-phase distribution points where reliable isolation and protection are critical
• Remote or hard-to-access electrical rooms where a robust, integrated disconnect is advantageous

How it works and practical use cases

The FDPWS364J serves as a dedicated disconnect that can be paired with compatible fuses to provide precise overcurrent protection while enabling quick isolation during maintenance or fault events. In everyday operation, it helps prevent nuisance tripping and reduces the time needed to diagnose issues on three-phase feeders. Ideal for scenarios where a single, reliable device must both disconnect and protect a branch circuit.

Installation and compatibility tips

• Plan for panel-mount installation within your switchgear or panelboard enclosure, ensuring clean access for operation and maintenance.
• Use with appropriate fuse elements to achieve the desired protection level for each branch circuit.
• Verify mounting clearances and alignment to ensure smooth operation and long service life in industrial environments.
