Siemens 3SB3802-0DA3 Push Button Start Stop Switch

Siemens 3SB3802-0DA3 is a 22 mm program plastic enclosure designed to house a two-position Start/Stop control, featuring a gray top and two integrated pushbuttons that align with the Siemens 3SB3 family. The A position is a red pushbutton labeled “O” with one normally open (1NO) contact, while the B position is a green pushbutton labeled “I” with one normally closed (1NC) contact, enabling a straightforward Start/Stop wiring setup in automation circuits. The enclosure supports vertical mounting with two command points and includes a front ring for finished assemblies. Cable routing is flexible through two M20 entries for top and bottom wiring, making it suitable for compact control panels. With IP65 protection, the enclosure resists dust and water jets in factory environments, delivering reliable operation in typical machine control applications such as conveyors, presses, or other automated equipment requiring a clearly labeled Start/Stop interface that remains visually consistent with Siemens signaling hardware. This model is designed to house 22 mm pushbutton components and is intended for panel builders seeking a standard, rugged Start/Stop solution that integrates seamlessly with Siemens 3SB3 actuators and signaling devices.
