Industrial 3D10UM NSMP Circuit Breaker

Altech 3D10UM is a UL 508-listed three‑pole manual motor controller designed for use as a motor disconnect in industrial panels. It provides a 10 A rated current and is part of the UM series, engineered for DIN‑rail mounting in compact enclosures. The device is rated for 480Y/277 VAC operation at 50/60 Hz and delivers thermal‑magnetic protection across a three‑phase circuit, ensuring all poles interrupt together for safe shutdown. With a per‑pole width of 17.5 mm, the 3D10UM supports dense panel layouts while meeting safety standards that require a formal motor disconnect. Typical applications include protection and control of AC motors in manufacturing lines, conveyors, pumps, and other industrial equipment where UL 508 compliance and a dedicated disconnect are preferred for serviceability and safety. The 3D10UM designation identifies a 3‑pole, 10 A version within Altech’s UM family, which emphasizes compact protection for branch circuits in industrial equipment and panels.
