Eaton DH364NRKA1480 Heavy Duty Fusible Safety Switch - UL Listed
Part Number: DH364NRKA1480
Quick Summary
DH364NRKA1480 is a heavy-duty fusible safety switch designed to disconnect and protect three-phase power systems in industrial settings. This solution addresses the persistent challenge of safe isolation during maintenance and energization events that disrupt production. UL Listed, NEC 230.62 barrier compliance, and a NEMA 3R enclosure ensure reliable performance in outdoor and demanding environments. Designed for 200 A, 600 V service, it accepts #6-250 kcmil Cu/Al conductors and provides a neutral for four-wire control circuits. The result is faster, safer installations and stronger regulatory alignment, supporting uptime, personnel safety, and lower total cost of ownership across industrial control panels and motor control centers.

Eaton Specification Sheet - DH364NRKA1480
Selling Policy 25-000 - Distribution and Control Products and Services
The 200 A amperage rating with a three-pole, four-wire configuration provides robust motor disconnect and protection for demanding loads, enabling precise control of motors up to 150 hp at 480/600 V and reducing nuisance tripping. The NEMA 3R enclosure, painted galvanized steel, offers weather resistance and vandal protection, extending service life in outdoor switchgear installations and wash-down environments to lower maintenance frequency. With a 600 V rating and horsepower support of 50/125/150 hp (1/3PH @ 480, 600 V), it accommodates a range of industrial drives, simplifying long-term lifecycle planning and panel commonality. The fuse class provision is Class H and it is fusible with neutral, delivering safer fault clearing and better coordination with control circuits. UL Listing and NEC 230.62 barrier compliance promote regulatory alignment and safer installations, while the compact 11.25 in L x 16 in W x 27.63 in H footprint and 52 lb weight enable straightforward substitution in existing panels, supporting retrofit and expansion projects without extensive cabinet modifications.
