The Siemens 3SB5400-7CE 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 operations such as ON, OFF, RUN, or FAULT in automation systems.
Despite sometimes being referred to under “legend plate” naming, the 3SB5400-7CE is actually an integrated LED indicator lamp holder, not a labeling plate. It is part of Siemens’ modular 22 mm SIRIUS ACT control device system, used widely in industrial automation and panel building applications.
This variant typically features a 24 V AC/DC supply with green LED illumination, offering reliable and energy-efficient signaling.
The Siemens 3SB5400-7CE is widely used in:
Green LED provides strong visibility for “running / healthy / ready” system states.
Built for continuous operation in harsh electrical environments.
Low power consumption with long operational life reduces maintenance needs.
Compatible with Siemens SIRIUS ACT 22 mm pushbutton and indicator systems for easy panel design.
Although often searched as a “legend plate,” the 3SB5400-7CE is not a labeling accessory. It is an illuminated LED indicator lamp module used for status signaling in control panels.
