Siemens 3UA6001-2W Overload Relay

Siemens 3UA6001-2W is a thermally delayed overload relay designed for motor protection in AC circuits, part of the Siemens 3UA6 family. It safeguards motors rated 63 to 90 A and is sized as S6, intended for mounting to compatible Siemens contactors or starters. This model is built for stand-alone installation with compatible devices (such as 3TB50/52 series) and includes one normally open and one normally closed auxiliary contact to signal protection status to control circuits. In practical use, the 3UA6001-2W provides reliable thermal protection by interrupting the main circuit when overheating is detected, helping prevent motor damage and unplanned downtime in applications like conveyors, pumps, and fans where compact, standalone overload protection is required alongside Siemens equipment.
