Eaton DH363URK Non-Fusible Heavy Duty Safety Switch

The Eaton DH363URK Non-Fusible Heavy Duty Safety Switch is a 3‑pole, 363 A manual disconnect designed to isolate and protect electrical circuits without integrated fuses, delivering secure power disconnection for three‑phase systems up to 600 VAC (model dependent). Built for industrial and commercial distribution, it supports maintenance lockout, emergency shutdown, and safe servicing of branch circuits and equipment feeds in environments such as factories, warehouses, commercial buildings, motor control centers, lighting panels, pump systems, and HVAC equipment. Its load and line lug terminals provide secure cable connections, and the manual ON/OFF handle includes a lockable provision to prevent accidental reenergizing during service. The enclosure is industrial duty and can be mounted on a surface or within a panel, offering flexible installation in control cabinets or equipment rooms. The unit is UL/CSA certified, aligning with common electrical safety practices for circuit isolation without fusible protection. For reference, common replacements include Eaton DH364URK, Square D H364 Non‑Fusible Safety Disconnect, and Siemens HF364 Non‑Fusible Safety Switch.
