Siemens 3SB3902-1EQ Inscription Plate Pushbutton

Product Description

The SIEMENS 3SB3902-1EQ is an inscription plate designed for use with 22mm and 12.5mm pushbutton and selector switch assemblies. Inscription plates provide a labeling surface directly on the operator, allowing panels to be clearly marked for function identification without additional tags or separate labels. At 0.22 pounds, the plate is a lightweight add-on component typically installed by electricians and control panel builders during final assembly or retrofit work. It fits into compatible pilot device fronts as part of the 3SB3 series operator accessory system.

This inscription plate is suited for industrial control panel applications including machine tool enclosures, motor control centers, and process control stations. It is used in both original equipment manufacturing and field service scenarios where operator station labeling must meet plant or facility identification standards. The 3SB3902-1EQ is installed as part of a complete pushbutton or selector switch assembly rather than as a standalone device.

Key Features

• Fits 3SB3 series pushbutton and selector switch operator assemblies
• Provides a dedicated labeling surface for panel function identification
• Lightweight construction at 0.22 pounds for easy handling during assembly
• Designed for flush integration into compatible pilot device fronts
• Suitable for both OEM panel builds and field retrofit installations

Compatibility

Designed as an OEM-style accessory for use with compatible 3SB3 series pushbutton and selector switch operator assemblies requiring inscription plate labeling components.

Installation Notes

Installation is typically performed by a licensed electrician or qualified control panel technician. De-energize and lock out the control panel before servicing any pilot device assembly. The inscription plate snaps or slides into the operator front per the assembly design — do not force the component as this may damage the pilot device body. Follow applicable NEC and local electrical code requirements for industrial control panel construction.
