Siemens KT4050P is a 40-amp, 3-pole, 600-volt AC, NEMA 3R heavy-duty safety switch designed for disconnecting and protecting electrical circuits in industrial environments. It features a 40-amp continuous current rating and a 600-volt AC maximum voltage rating, housed in a rugged, NEMA 3R-rated enclosure for outdoor or indoor use. The switch utilizes a visible blade, quick-make/quick-break mechanism with a 10,000 AIC short-circuit current rating, and is constructed with a galvanized steel enclosure for corrosion resistance. It complies with UL 98 and CSA C22.2 No. 4 standards, ensuring reliable performance in motor control centers, panelboards, and other power distribution systems. Typical applications include commercial and industrial facilities requiring a dependable, non-fusible disconnect for branch circuit protection.
