Product description

The Siemens 3SB3400-1QA is an actuator and indicator component featuring an integrated LED with a yellow lens. It operates at 110V AC and includes a lamp holder with screw terminals for easy wiring. This component is part of the older SIRIUS system and has been superseded by the SIRIUS ACT 3SU1 series, with 3SU1401-1BC30-1AA0 as the recommended successor.

This yellow indicator is ideal for signaling specific conditions or status in industrial machinery, control panels, and electrical systems where a 110V AC supply is available. Its bright yellow light ensures high visibility for operators.
