Siemens 3SB3801-2DG3 Metal Enclosed Emergency Stop
The Siemens 3SB3801-2DG3 is a metal enclosed command device for 22mm round installations, featuring a prominent 40mm red emergency stop mushroom pushbutton. This unit has a yellow plastic enclosure top and is equipped with one normally closed (NC) contact. The rotate-to-unlatch mechanism ensures a safe and intentional reset. Connections are made via screw terminals, and the enclosure provides M20 cable entries at the top and bottom. This product is phased out, with SIRIUS ACT 3SU1 being its successor.
This robust assembly is ideal for safety-critical applications in manufacturing, process automation, and heavy industry where reliable emergency stop functionality within a durable metal enclosure is required. The red mushroom head provides clear visual indication of the emergency stop function.
