3SU1400-1AA10-1BA0

The 3SU1400-1AA10-1BA0 is a contact module from Siemens' SIRIUS ACT series of 22mm pushbuttons and signaling devices, designed to snap onto the back of a compatible SIRIUS ACT actuator, such as a pushbutton or selector switch, to complete a functioning control station. It provides one normally open (NO) contact element, letting the actuator switch a control circuit when pressed or turned. Its snap-on design allows tool-free, one-handed installation, making it quick to assemble or service pushbutton and selector switch stations. Electrically, the 3SU1400-1AA10-1BA0 is rated for at , with performance varying by voltage and switching category (AC-12/AC-15 for AC circuits, DC-12/DC-13 for DC circuits) to suit different control and signaling applications. Its silver alloy contacts and momentary action provide reliable switching performance, and its rated insulation voltage of 500V makes it suitable for a wide range of industrial control circuits. Mechanically, the 3SU1400-1AA10-1BA0 uses screw terminals for wiring and mounts to the front plate assembly behind a compatible SIRIUS ACT actuator head. Its IP20/IP40-rated housing and vibration-resistant design suit demanding industrial and outdoor environments, and it serves as a direct replacement for Siemens' earlier 3SB3400-0B contact block in existing control stations.
