FAQs
For proper installation, mount the two-pole switch inside a NEMA 4X enclosure using corrosion-resistant 304 stainless steel. Use the fusible without neutral configuration with Class H fuses as specified, and ensure the unit operates at 240 V with 100 A rating. Verify compatibility with your panel layout and space constraints, and plan for standard fuse/time-delay protection where applicable.
The DH223FWK supports configurations suitable for both 1- and 3-phase systems. HP ratings vary by phase and fuse timing, with a maximum rating indicated as 7.5 to 30 HP in the data sheet depending on the exact configuration (1P vs 3P and time-delay fuse usage at 250 Vdc). Confirm your motor plant requirements and select the appropriate fuse timing and phase to match your drive.
This switch is UL Listed, indicating compliance with recognized safety standards. It also features a NEMA 4X enclosure suitable for protected outdoor and corrosive environments. The 304 stainless steel enclosure further enhances corrosion resistance, supporting maintenance-free operation in harsh facilities and simplifying compliance documentation for audits.
Maintenance should focus on periodic fuse inspection and replacement with Class H fuses compatible with 100 A ratings. Inspect the enhanced visible blade for clear status indicators during service, and check enclosure integrity for any corrosion or seal wear. Maintain a small stock of standard fuses and contact safety-switch support for any specialized fuse configurations.
The combination of a corrosion-resistant 304 stainless steel enclosure, NEMA 4X protection, UL Listed compliance, and a robust fusible circuit design minimizes unplanned outages and enhances personnel safety. Its two-pole, 100 A, 240 V configuration supports reliable protection for motors and controls, reducing fault propagation and enabling faster maintenance in demanding manufacturing and processing environments.
