The Siemens 3SB5400-7CG is a SIRIUS ACT / 3SB5 series illuminated indicating lamp module used in industrial control panels and operator stations. It is designed to provide clear visual status indication for machine states such as ON, OFF, RUN, or FAULT in automation systems.
Although it is sometimes listed under “legend plate” naming, the 3SB5400-7CG is not a labeling plate. It is an integrated LED lamp holder module used in Siemens 22 mm modular pushbutton systems for visual signaling.
This variant typically operates on 24 V AC/DC and comes with a white LED indication, making it suitable for general-purpose status signaling in industrial environments.
The Siemens 3SB5400-7CG is widely used in:
White LED provides a universal signal suitable for general machine status and multi-purpose indication.
Designed for continuous operation in harsh electrical environments with stable output.
Low power consumption with long operational life reduces maintenance needs.
Compatible with Siemens SIRIUS ACT 22 mm modular pushbutton systems for fast installation and standardized panel design.
Even though it is sometimes called a “legend plate,” the 3SB5400-7CG is not a physical labeling plate. It is an illuminated LED indicator module used for signaling in control panels.
