Eaton DH263FRK Heavy Duty Fusible Safety Switch - UL Listed
Part Number: DH263FRK
Quick Summary
Eaton heavy duty fusible safety switch provides safe, rapid isolation of electrical circuits for industrial control panels and outdoor installations. Too often downtime and safety incidents arise from improper switching, missing neutral paths, or undersized enclosures. UL Listed protection, a NEMA 3R enclosure, and Class H fuse design help ensure reliable operation in harsh environments. This solution supports high-integrity motor circuits and preventive maintenance programs, while aligning with procurement goals for performance, compliance, and lifecycle costs. Industry engineers value its compact footprint and flexible wiring options for panel builders and retrofit projects. With two poles, a 600 V rating, and Cu/Al wire compatibility up to #1/0, it streamlines installation and future upgrades.

Feature → Business Impact → Application: The DH263FRK delivers a 100 A amperage rating with two-pole, two-wire operation and fusible without neutral using Class H fuses at 600 V, enabling selective protection for motor feeders while reducing arc-flash risk and simplifying fuse coordination. This translates to faster fault isolation and lower downtime for critical lines, particularly in mid-size motor drives and feeders in controlled industrial spaces. Application: Ideal for plant floors, machine lines, and outdoor enclosures where reliable switching is required. Feature → Business Impact → Application: Wire size compatibility supports Cu/Al conductors from #14 to #1/0, offering flexible field wiring and easier retrofits. Benefit includes reduced cabling complexity and lower rewiring costs during expansion or maintenance. Application: Suitable for new builds and retrofits in control panels and switchgear assemblies. Feature → Business Impact → Application: NEMA 3R enclosure with painted galvanized steel provides weather resistance and corrosion protection. Impact includes safer outdoor installations and consistent performance in damp or dusty environments. Application: Outdoor service entrances, equipment rooms, and exposed industrial locations. Feature → Business Impact → Application: Compact footprint with dimensions of 22.5 in L, 21.99 in H, 12.75 in W and a weight of 17 lb enables easier mounting and handling. Benefit includes faster installation, reduced panel integration time, and easier maintenance access. Application: Panel builders and machine builders working in space-constrained environments. Feature → Business Impact → Application: Max HP rating of 30–40 hp (1PH at 480/600 V TD/600 Vdc) ensures alignment with typical motor loads and drive systems. Benefit includes optimized protection without over-sizing, improving energy efficiency and lifecycle cost. Application: Motor control centers, feeders, and machine lines with medium horsepower motors. Feature → Business Impact → Application: UL Listed certification and a defined warranty (one year from installation or eighteen months from shipment) strengthen procurement confidence and regulatory compliance. Benefit includes reduced risk in specifications and service planning. Application: Industrial procurement, compliance audits, and service contracts.
