Eaton / Cutler-Hammer FDPW368 – 1200A, 3-Pole Branch Fusible Panel-Mount Switch – FDPW Series

Engineered for demanding industrial environments, the Eaton / Cutler-Hammer FDPW368 delivers authoritative load isolation and reliable overcurrent protection in a compact 3-pole, 1200A branch fusible panel-mount switch. As part of the FDPW Series, this device is built to endure the rigors of switchboards and panelboards where safe, decisive power disconnection is essential.

Key advantages that matter in the field

• High-current capability — rated at 1200A, designed to protect major feeders and high-load circuits without compromising portability or fit within standard panel spaces.
• Three-pole isolation — simultaneously disconnects all three phases for complete, reliable phase isolation and safer maintenance on multi-phase systems.
• Panel-mount convenience — engineered to integrate directly into existing switchgear or panelboard layouts, streamlining installation and reducing enclosure clutter.
• Fusible protection — provides fast, visible fault interruption with field-replaceable fusible links, enabling quick restoration of service after a fault.
• Rugged, industrial design — built for continuous service in demanding environments where durability and consistent performance are non-negotiable.
• Part of the FDPW Series — a trusted family of fusible switches known for dependable protection and straightforward maintenance in industrial power distribution.

Ideal applications

• Switchboards and panelboards in manufacturing floors, processing plants, and heavy electrical rooms
• Distribution points that require reliable feeder protection and a clearly defined disconnect
• Critical support circuits where quick, safe isolation minimizes downtime during maintenance or fault conditions

How it works

The FDPW368 functions as a robust branch fusible switch: when the system operates normally, the device provides a solid, well-defined disconnect path. In the event of an overcurrent, the fusible links melt in a controlled manner to interrupt current, while the three poles ensure all phases are opened simultaneously. This combination delivers not only protection, but a clear, unambiguous isolation point for safe servicing and fault containment.

Installation and maintenance considerations

• Ensure your panel enclosure has compatible space for a 3-pole, 1200A panel-mount assembly within the FDPW Series family.
• Use only FDPW-series fusible links to maintain protection integrity and compliance with standard configurations.
• Plan for straightforward field maintenance: fuse replacement is designed to be performed without extensive downtime, helping you minimize disruption during fault events.
