E4809-032-400-E by Okuma

The Okuma E4809-032-400-E board offers an industrial-grade solution for high-current three-phase power distribution, seamlessly integrating into automation environments as part of the E4809 CNC Boards series. Designed to operate at a 400V voltage rating with a 32A current rating, it delivers consistent performance under continuous load conditions for advanced manufacturing systems. The board features a screw terminal connection type that ensures reliable wire termination and simplifies installation, reducing downtime in field service or assembly. With a durable polyamide housing material and a compact form factor, the E4809-032-400-E supports versatile panel mounting in industrial enclosures. This assembly has been engineered by Okuma to meet the rigorous demands of modern industrial automation and control applications.

Technical implementation details are defined by a precise array of specifications: the board complies with IEC 60309 compliance to guarantee compatibility with global power standards. It employs nickel-plated brass contact material to minimize contact resistance and enhance corrosion resistance. The 3P+E mounting type supports three-phase plus earth configurations, and it operates across both 50/60Hz frequency power networks. The overall mass of 220g weight minimizes added load on support structures, while the low-profile design eases integration into tight panel layouts. Each specification is validated for reliability in heavy-duty industrial contexts.

Operational resilience is achieved through an IP44 protection degree that shields internal components from solid ingress above 1 mm and splashing water from any direction. The E4809-032-400-E maintains stable service within a -25°C to +40°C operating temperature range, ensuring functionality in cold storage areas or heated production floors. Vibration and thermal stresses are mitigated by the robust polyamide enclosure, preserving contact integrity under mechanical load. The screw terminal configuration delivers secure clamping force to conductors, preserving electrical continuity during shock and vibration events common in industrial machinery. The board’s continuous rating and material choices provide extended service life in demanding power distribution roles.

Integration into control cabinets and power distribution panels is straightforward: the panel mount feature aligns with standard enclosure cutouts and DIN panel layouts. This board is suited for applications in CNC machinery, mobile power units, temporary site installations, and stationary industrial automation systems. Its compliance with global standards and rugged construction makes it an ideal component for engineers specifying high-reliability power interfaces. By combining modular installation with robust performance, the E4809-032-400-E enhances system uptime and simplifies maintenance in diverse industrial environments.
