Eaton / Cutler-Hammer FDP326TR – 600A, 3-Pole Vertical Main Fusible Panel-Mount Switch – FDP Series

Eaton / Cutler-Hammer FDP326TR is a rugged 600A, 3‑pole vertical main fusible panel‑mount switch from the FDP Series, engineered for switchboards and panelboards that demand reliable load isolation and definitive overcurrent protection. This model is configured for vertical installation and carries the lineage of the legacy Westinghouse FDP vertical main switch, offering familiar architecture for upgrades and replacements.

Key features

• 600A main rating for decisive control of high‑current feeders in three‑phase systems.
• 3‑pole configuration supports standard 3‑phase distribution with consistent switching performance.
• Vertical panel‑mount installation optimizes space in tight electrical rooms and aligns with common panelboard layouts.
• Fusible main switch provides integrated overcurrent protection at the feeder level, simplifying protection architecture.
• FDP Series lineage and compatibility with FDP hardware, preserving the installation philosophy you know from legacy FDP designs.

Ideal applications

Designed for switchboards and panelboards in industrial environments where dependable isolation and protection are critical. In facilities with heavy three‑phase loads, the FDP326TR serves as the primary disconnect for feeders, enabling safe maintenance, testing, and fault isolation while minimizing downtime.

Why this matters

• Reliability under load—a robust main switch that maintains clear, decisive control over high‑amperage circuits.
• Efficient layout—vertical mounting supports compact, accessible installations without compromising serviceability.
• Streamlined protection—integrated fusible protection at the main path reduces the need for additional protective devices in upstream gear.

Who benefits

Electrical engineers, panel builders, facilities managers, and OEMs who work with 3‑phase power distribution will appreciate the FDP326TR for its proven vertical‑install design, industrial durability, and straightforward integration with FDP Series components.
