3SB3803-2DB3 SIEMENS

The 3SB3803-2DB3 from Siemens, now a phased-out product, is a robust metal enclosure designed for 22mm command and signaling devices. This enclosure features three command positions, offering a versatile solution for various control applications. The top part of the enclosure is finished in a neutral gray color, providing a clean and professional aesthetic. Position A is equipped with a red pushbutton, clearly marked with the symbol "O", typically indicating an off or stop function. Position B features a black pushbutton labeled with "I", commonly used to signify an on or start function. Position C also has a black pushbutton, labeled with "II", potentially indicating a second on state or another distinct function. The enclosure includes one normally open (1NO) contact, enhancing its functionality for control circuits. Siemens recommends the SIRIUS ACT 3SU1 series as a successor, with the preferred replacement being model 3SU1853-0AD00-2AB1, ensuring a seamless transition and continued performance. This enclosure is ideal for applications requiring durable and reliable control interfaces.
