Feature: The DH263FDKW uses a two-pole, two-wire design with cartridge fuse configuration rated at 100 A and suitable for #14-#1/0 Cu/Al conductors. Business Impact: This arrangement minimizes panel depth and wiring complexity, accelerating installation while improving fault isolation in distribution panels and motor control centers. Application: Effective for heavy commercial and industrial environments where uptime matters, including motor starters, process lines, and large conveyors; supports 1PH operation up to 480–600 V and HP ratings up to 40 hp on 1PH lines. Feature: A painted galvanized steel, NEMA 12 enclosure provides robust dust and splash protection. Impact: Reduces corrosion risk and maintenance costs in demanding facilities such as manufacturing floors, outdoor-rated spaces, and damp electrical rooms. Application: Ideal for distribution panels, service disconnects, and panel boards within heavy industry. Feature: Window and visible blade enable positive status indication and easier lockout-tagout verification. Impact: Cuts misoperation risk and speeds servicing, minimizing unplanned downtime. Application: Critical for routine maintenance, inspections, and safety-compliant shutdown procedures. Feature: Fuse class provision is cartridge, configured for fusible without neutral, with 2 wires and 600 V max rating. Impact: Supports safe switching of feeder circuits and straightforward spare fuse stocking; reduces miswiring and requirement for neutral conductors in simple disconnects. Application: Suitable for feed-disconnects in motor control centers and branch circuits up to 100 A. Feature: Durable construction and warranty support from Eaton; UL Listed and NEMA 12 compliance. Impact: Provides long-term reliability and predictable service life, with a one-year (or policy-based) warranty and access to Eaton’s technical support and replacement parts. Application: Facility-wide protection programs and asset-value preservation for critical production lines.
