Siemens 3SB5400-7HG Lamp Holder with Integrated LED – 220 V DC White

The Siemens 3SB5400-7HG lamp holder with integrated LED is a compact industrial signalling component designed for machine-control panels, operator stations and industrial automation systems. It features an integrated white LED, is designed for 220 V DC operation, and uses a screw terminal connection with front plate mounting.

This combination provides a practical solution for applications where operators need a clear visual indication of machine, process or equipment status. The white LED can be assigned to general status, equipment availability, process indication or another defined operating condition according to the control philosophy of the application.

Integrated White LED for Clear Visual Indication

The Siemens 3SB5400-7HG combines the LED light source and lamp holder into a single compact component. This integrated design simplifies the selection and installation of the visual indicator within a compatible operator-control assembly.

White illumination can be used for a range of machine and process indications, depending on the control-panel design. Typical applications may include:

• General machine status
• Equipment availability
• Control-system status
• Process indication
• Power or auxiliary indication
• Operator information
• Machine operating condition

The exact function assigned to the white LED should be clearly defined in the machine's control documentation so operators can interpret the indication correctly.

220 V DC Operating Voltage

The 3SB5400-7HG LED lamp holder is designed for 220 V DC operation, making it suitable for compatible industrial control systems and signalling circuits using the specified DC supply.

The integrated LED provides a dedicated visual signalling solution for operator stations and control panels. Before installation, the available supply voltage and control circuit should be checked against the product requirements.

Correct electrical connection is essential for reliable operation. Wiring and installation should be carried out using suitable electrical practices and according to the requirements of the complete control system.

Screw Terminal Connection

The screw terminal connection provides a practical method for connecting the LED indicator to the control circuit.

Screw terminals are widely used in industrial control panels because they provide secure conductor termination and convenient access during inspection, testing and maintenance.

For electricians, panel builders and system integrators, this makes the Siemens 3SB5400-7HG suitable for straightforward integration into compatible operator-control wiring.

Appropriate conductor selection, termination and tightening procedures should be followed according to the applicable electrical installation requirements.

Front Plate Mounting

The front plate mounting configuration allows the lamp holder to be installed directly on the front of a compatible control panel or operator enclosure.

This positioning keeps the white LED clearly visible to operators and allows machine status to be monitored without opening the electrical cabinet.

The lamp holder can be combined with compatible Siemens 3SB5 pushbuttons, switches and contact blocks to create a consistent and professional operator interface.

Applications of Siemens 3SB5400-7HG

The Siemens 3SB5400-7HG white LED lamp holder can be used in a wide range of industrial applications, including:

• Machine-control panels
• Industrial automation systems
• Production machinery
• Packaging equipment
• Conveyor systems
• Manufacturing equipment
• Process-control systems
• Motor-control panels
• Local operator stations
• OEM-built machinery
• Industrial signalling systems
• Equipment status indication

It is particularly useful where a white visual indication is required to communicate a defined machine, process or equipment condition.

Suitable for OEMs and Panel Builders

The Siemens 3SB5400-7HG LED lamp holder is suitable for OEM machine builders, electrical panel manufacturers, system integrators and industrial maintenance professionals.

For new machine-control projects, it can be incorporated into a local operator station as a dedicated white status indicator. For replacement and maintenance applications, it can be considered where a compatible Siemens 3SB5 LED signalling component designed for the specified DC supply is required.

Its integrated LED construction provides an all-in-one signalling solution, helping simplify operator-panel design and component selection.
