Siemens 3SB14 00-5M Pilot Light Module Transformer

Siemens 3SB14 00-5M Pilot Light Module Transformer is a compact transformer designed to drive a pilot lamp inside Siemens 3SB14 pilot-light assemblies. It accepts 110–127 VAC mains at 50/60 Hz and steps the voltage down to 6 V AC to power the indicator lamp, with a 2 W power rating. This module is part of the 3SB14 family of lamp modules and provides an integrated, low-voltage supply for status indication in industrial control panels, equipment enclosures, and machine dashboards that use Siemens lampholders. When paired with compatible 3SB14 lampholder components, it enables a compact, plug-in indicator solution that simplifies panel wiring and reduces the need for separate external transformers in control circuits. The 3SB14 00-5M variant is one of several 3SB14 pilot-light options designed for 110/127 VAC operation and 50/60 Hz environments, ensuring compatibility with standard North American and many international mains supplies where 110–127 V is present.
