Eaton / Cutler-Hammer FDPWS364R – 200A, 3-Pole Branch Fusible Panel-Mount Switch – FDPWS Series

Eaton / Cutler-Hammer FDPWS364R is built for rugged industrial environments where dependable power isolation and precise current protection matter. This 200A, 3-pole branch fusible panel-mount switch from the FDPWS Series delivers a compact, ready-to-integrate solution for panelboards and switchboards that demand reliable, safe operation across all three electrical phases. What makes this FDPWS364R stand out - 3-pole design for full-phase isolation: With three independently controlled poles, this switch disconnects all conductors simultaneously, helping you meet stringent safety and maintenance requirements in 3-phase systems. - Integrated fusible protection for branches: The FDPWS Series combines switching and fusing in a single, streamlined package, reducing wiring complexity while providing immediate overcurrent protection for branch circuits. - Panel-mount convenience: Designed to mount directly into panels or switchboards, it simplifies retrofits and new installations alike, delivering a clean, professional installation with minimal enclosure space needed. - Industrial-duty reliability: Built to endure the demands of active electrical environments, the FDPWS364R is engineered for repeated operation, demanding loads, and long service life where uptime is critical. Ideal use scenarios - Switchboards and panelboards that require both reliable load isolation and overcurrent protection in a single, compact assembly. - Machine control panels and centralized distribution nodes in manufacturing facilities where 3-phase protection is essential. - Retrofit projects where aging protection schemes need a modern, fusible disconnect that fits standard panel profiles without extensive rewiring. - Any application needing a robust 200A disconnect that can be integrated into existing FDPWS-series configurations for consistent performance. Why this design matters in practice - Simplified protection strategy: By pairing fusing with a panel-mount switch, you gain a straightforward, easy-to-maintain path for protecting branch circuits while ensuring safe, verifiable isolation during service. - Clear fault response: In the event of overcurrent, the integrated fusible path provides rapid protection, helping minimize damage to downstream equipment and reducing downstream downtime. - Consistent, scalable architecture: As part of the FDPWS Series, the FDPWS364R aligns with other FDPWS components, enabling clean, scalable layouts across multiple panels and projects. Practical tips for installation and use - Plan for full-load switching across all three phases to ensure complete isolation when needed; the 3-pole design is specifically intended for synchronized disengagement. - Pair with appropriate branch fuses compatible with the FDPWS architecture to maintain intended protection levels and compliance with your panel design. - Ensure secure panel mounting and proper enclosure clearances to maintain performance and ease of access for maintenance. - Use as part of a thoughtful protection strategy in new builds or upgrades, aligning with your system’s current and anticipated load profiles.
