Industrial 3D10UM Circuit Breaker

Altech 3D10UM is a three-pole, UL 508-listed manual motor controller that doubles as a circuit-breaker-style disconnect for small motor circuits in industrial panels. Designed for DIN rail mounting, each pole occupies 17.5 mm of rail width (roughly 52.5 mm total), with a rugged thermal-magnetic trip (D-Trip) and a rated current of 10 A. The device operates on 50/60 Hz at up to 480Y/277 VAC and accommodates a broad AC current range from 0.3 to 60 A, while also offering DC ratings under specific conditions: 0.3-25 A (1P 42 VDC; 2P 80 VDC) and 30-60 A (1P 24 VDC; 2P 60 VDC). With a 10 kA short-circuit withstand capacity and UL 508 listings, it is suitable for applications such as motor starting, across-the-line switching, AC general use, and protection of ballast and incandescent lamp loads.
