This is a brand new Square D HU361RB N disconnect switch. It's a 30 Amp, 600 Volt, 3-phase non-fused switch inside a NEMA 3R enclosure (good for outdoor use, protects against rain and sleet). Non-fused means it doesn't include fuses – it's just a safety disconnect to shut off power for maintenance. A common, reliable industrial and commercial electrical component for motor controls, HVAC units, or machinery. Always have a qualified electrician handle installation.
