Altech Corp. 3G25UM Three Pole Circuit Breaker

Altech Corp. 3G25UM is a UL 508-listed, three-pole thermal-magnetic circuit breaker with a G-Curve (G-Trip) characteristic, rated at 25 A for 480Y/277 VAC three-phase service. It is designed for DIN-rail mounting and intended as a motor disconnect in industrial control panels, providing both overload protection and short-circuit protection in a compact package. The 480Y/277 V rating makes it suitable for distribution panels that feed three-phase motors in factory automation, HVAC, and equipment rooms, where startup surges are a consideration and a dedicated disconnect is required by code. With its 3-pole configuration and UL 508 listing, the 3G25UM integrates into standard control-panel layouts for protecting motors, pumps, conveyors, and other three-phase loads in industrial environments.
