ABB TH4323SS Temperature Switch Stainless Steel

ABB TH4323SS is a three-pole, 100 A fusible disconnect switch housed in a stainless-steel NEMA 4X enclosure, engineered for rugged indoor or outdoor service in industrial and commercial facilities. The unit is designed for 240 VAC operation and supports motor loads up to 15 hp, providing safe isolation with a fusible path—fuses are installed in the switch according to the electrical design. Built to stand up to harsh environments, the stainless-steel enclosure resists corrosion and weathering, while the NEMA 4X rating offers protection against ingress and washdown in demanding sites. As part of ABB's heavy-duty safety-switch lineup, TH4323SS is intended for use as a functional disconnect and protection device on power feeders and branch circuits, enabling quick shutoff for maintenance or emergency isolation. Typical applications include outdoor or moisture-prone installations in manufacturing, warehousing, and process facilities, where durable, code-compliant isolation is required and a reliable 3‑pole, 240 VAC, 100 A solution is needed.
