FAQs
The DH223FRK fits in standard control panel configurations with a 22.5 inch depth, 12.75 inch width, and 9 inch height footprint, weighing 26 pounds. Installers should plan for a two-pole, two-wire 240V configuration, use appropriate fuses (Class H) for the intended HP load, and ensure the enclosure remains in a protected, code-compliant space consistent with a UL Listed product and a NEMA 3R rating. Provide clear blade visibility for safe operation during maintenance.
DH223FRK is rated for 100A at 240V. The maximum horsepower varies by configuration: 7.5 hp, 15 hp for single‑phase, and 15 to 30 hp for three‑phase operation when using standard fuse with time-delay at 250Vdc. This range supports a broad spectrum of motor loads, enabling safe isolation without overrating the switch for common industrial motors.
Yes. The enclosure is NEMA 3R rated and built from painted galvanized steel, providing protection against rain, dust, and corrosion in outdoor or damp locations. This makes it suitable for outdoor equipment housings and exposed installations where operator safety and reliable isolation are critical, while maintaining UL Listed compliance.
The DH223FRK carries UL Listed certification, indicating adherence to recognized safety standards for electrical switchgear. The NEMA 3R enclosure rating ensures the unit can withstand outdoor and damp environments, protecting internal components from weather and debris. These certifications matter because they help ensure compliance, reduce risk, and support code acceptance in industrial installations.
Maintenance is straightforward due to a robust galvanized enclosure and the availability of standard Class H fuses, enabling quick replacement and minimal downtime. The UL Listed, rugged design helps reduce unexpected failures, translating to lower maintenance costs and improved uptime over the equipment lifecycle. The 1-year warranty further supports total cost of ownership in routine service scenarios.
