The Siemens 3SB5400-7CL 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 operations such as RUN, STOP, FAULT, or READY in automation systems.
Although it is sometimes grouped under “legend plate” terminology, the 3SB5400-7CL is not a labeling plate. It is an integrated LED illumination module used in Siemens 22 mm modular pushbutton systems for status signaling.
This variant typically operates on 24 V AC/DC and features an amber LED, making it suitable for warning or caution indication in industrial environments.
The Siemens 3SB5400-7CL is widely used in:
Amber LED provides strong visibility for caution, standby, or intermediate machine states.
Designed for continuous operation in harsh electrical environments.
Low power consumption with long operational life reduces maintenance needs.
Compatible with Siemens SIRIUS ACT 22 mm systems for fast and standardized installation.
Despite “legend plate” wording in listings, the 3SB5400-7CL is not a physical label or engraving plate. It is an illuminated LED indicator module used for signaling in industrial control systems.
