Rugged enclosure and corrosion resistance lead to longer service life and lower maintenance in outdoor or damp environments. The painted galvanized steel housing complements the NEMA 3R rating, protecting critical components from weather, dirt, and impact while preserving performance over time. An enhanced visible blade improves operator awareness during routine operation and maintenance, reducing the risk of accidental energization and speeding up fault isolation in the field. This translates to safer work practices and faster troubleshooting, with measurable uptime gains in critical production lines. The dual-pole, two-wire design simplifies wiring and commissioning, minimizing installation time and reducing potential errors in busy panels. Compatibility with standard fusing and the Class L fuse provision ensures predictable protection coordination, supporting compliance with safety standards while enabling cost-efficient spare parts management. The enclosure supports substantial conductor sizes—up to four #1/0 to (4)750 kcmil Al—facilitating high-current connections in a compact footprint and reducing cabinet count in large systems. With 57.5 in length, 12.38 in height, and 27.5 in width, installers can plan space allocation precisely, improving overall plant layout and maintenance access.

FAQs
The DH227FRK is a two-pole, two-wire fusible safety switch with Class L fuse provision and fusible without neutral configuration. It accepts robust conductor sizes up to four #1/0 to (4)750 kcmil aluminum, enabling flexible, high-current terminations while keeping wiring manageable. This simplifies early procurement decisions and reduces on-site modification time during panel integration.
With an 800 A amperage rating at 240 V, the DH227FRK accommodates motor feeders and high-load circuits without frequent fuse changes. It supports up to 100 or 250 hp in three-phase service depending on fuse selection, offering design flexibility for diverse motor applications while maintaining safe, coordinated protection and quick fault isolation.
Yes. The DH227FRK carries UL Listed certification and uses a NEMA 3R enclosure, making it appropriate for outdoor and harsh indoor environments. The painted galvanized steel construction resists corrosion, while the enhanced blade visibility aids safe operation. These features help meet regulatory requirements and support reliable long-term performance.
Eaton provides a standard warranty of one year from installation or eighteen months from shipment, whichever occurs first. This, combined with UL Listed and NEMA 3R ratings, supports maintenance planning and budget forecasting. Access to Eaton product sheets and catalogs also aids in ongoing compliance and parts availability.
Key considerations include verifying the Class L fuse coordination, ensuring the fusible without neutral configuration matches the control scheme, and confirming conductor sizes up to four #1/0 to (4)750 kcmil Al fit the terminals. The Enhanced visible blade aids status checks, and the NEMA 3R enclosure protects the assembly in exposed environments, supporting safe, compliant operation.
