Eaton Crouse-Hinds EIDD3400 Disconnect Switch - Hazardous

Feature: The EIDD3400 delivers a 400 A amperage rating with a horsepower range of 50/125/250/350, enabling it to isolate motors and loads across common industrial drives. This broad motor ratings profile translates to measurable business impact: fewer devices to stock, simpler protection coordination, and reduced installation time. The unit supports 240-600 Vac and 250 Vdc, making it suitable for a wide variety of plant feeders and MCCs in hazardous areas, including oil, gas, chemical processing, and mining facilities. It also supports energy-efficient motor control strategies by providing a single, compliant disconnect across multiple line voltages. This compatibility supports energy efficiency and streamlined procurement across multi-site facilities. | Feature: It comes non-fused and with a built-in switch, delivering a compact, ready-to-wire isolation point. The non-fused design reduces maintenance complexity and eliminates external fuses, decreasing spare parts inventory and downtime during replacement. In practice, technicians can rapidly disconnect power for lockout-tagout procedures and safe maintenance without swapping fuses or adding components. This integrated approach also simplifies panel layouts and improves fault isolation during commissioning. | Feature: Copper-free aluminum construction provides corrosion resistance and durability in harsh environments, while maintaining a robust enclosure for long service life. This material choice reduces overall weight relative to copper-bearing alternatives and improves heat dissipation in enclosed spaces. The enclosure’s rugged design withstands vibration, temperature swings, and chemical exposure common in hazardous locations, delivering lower maintenance costs over the life of the asset. | Feature: The EIDD3400 is an enclosure-with-switch option that aligns with standard installation practices, including 17.19 in depth, 41.22 in height, and 13.49 in width, supporting compatibility with existing switchgear footprints. NEMA ratings 3, 3R, 4, 7, 9 and NEC/CEC compliance ensure readiness for hazardous and classified locations across global markets. The availability of design resources—3D CAD packs, spec sheets, and installation instructions—streamlines design reviews, reduces commissioning time, and helps procurement lock in a reliable, standards-driven solution.
