Square D HU361AWK Heavy Duty Safety Switch, 30A, 600V, 3-Pole, Non-Fusible, NEMA 12

The Square D HU361AWK is a heavy-duty safety switch designed for reliable disconnection in industrial and commercial electrical systems. This non-fusible, 3-pole switch is rated for 30 amps at 600 volts, making it suitable for applications requiring robust circuit isolation, such as motor controls, machinery, and power distribution panels. Housed in a NEMA 12 dust-tight enclosure, it provides protection against dust, dirt, and non-corrosive liquids, ideal for indoor environments like factories or warehouses. Key features include a visible blade design for easy status verification, a rugged steel construction for durability, and compliance with UL standards for safety. Advantages over similar products include Square D's reputation for reliability, quick-make/quick-break switching mechanism to minimize arc flash risks, and compatibility with various mounting options. Drawbacks may include its non-fusible nature, requiring separate overcurrent protection, and a higher initial cost compared to light-duty alternatives. Based on attached images, the unit appears used with minor wear, including some scratches and internal dust, but functional internals like the switch mechanism and auxiliary contact are intact. No parent/child assets are evident.
