The Siemens 3SB5400-7DG is a SIRIUS ACT / 3SB5 series illuminated indicator lamp module used in industrial control panels and operator stations. It is designed to provide clear visual status indication for machine states such as RUN, STOP, FAULT, or READY in automation systems.
Even though it is sometimes listed under “legend plate” naming, the 3SB5400-7DG is not a labeling plate. It is an integrated LED indicator lamp holder module used in Siemens 22 mm modular pushbutton systems for reliable visual signaling.
This variant typically operates on 110 V DC and features a white LED indication, commonly used for general-purpose or neutral status signaling in industrial environments.
The Siemens 3SB5400-7DG is widely used in:
White LED is commonly used for general-purpose signaling, auxiliary status, or system-ready indication.
Designed for continuous operation in harsh electrical environments with stable output and long service life.
Low power consumption with long operational life reduces maintenance requirements.
Compatible with Siemens SIRIUS ACT 22 mm systems for fast installation and standardized panel design.
