Altech 1D10UM Circuit Breaker

Altech 1D10UM is a 1-pole, 10 A miniature molded-case circuit breaker designed for DIN-rail mounting in 277 VAC control panels. Part of the V-EA Series with D-Trip (D-Char) characteristics, it delivers thermal-magnetic protection for motor and general circuits, tripping quickly on overloads or short circuits while meeting UL 508 requirements for industrial equipment. Rated for 277 VAC, this 1-pole device features a 10 kA short-circuit interrupting capacity, making it suitable for branch protection in 277 VAC distribution networks. The compact 1P, DIN-rail form factor enables easy integration with other DIN-rail components in compact control cabinets, while the D-Trip characteristic provides precise protection curves for motor loads and general purpose circuits. Typical applications include motor control circuits, panel boards, and other industrial automation installations where reliable overcurrent protection on a DIN rail is required. This Altech breaker is designed to be used where UL508-compliant overcurrent protection is needed in 277 VAC systems, delivering dependable performance in demanding industrial environments.
