Siemens 52AATG3B Lighting Module

Siemens 52AATG3B Transformer Light Module is a 120 VAC green LED indicator designed for 30 mm panel installations and using a BA9s socket terminal for easy replacement. Marketed as a 30 mm light module accessory for CL52 control panels, this unit provides a compact status indication within Siemens automation environments. The green LED lamp is housed in a 30 mm module footprint, compatible with BA9s bases to retrofit or replace indicators in Siemens panels and equipment. Typical applications include panel-mounted status signaling on electrical controls and automation gear, where a durable, replaceable pilot light is needed in 120 VAC circuits. When selecting indicator lighting for Siemens CL52 or related assemblies, the 52AATG3B offers a green LED option within the transformer light module family, combining straightforward installation with a reliable visual cue for machine state or process conditions. Designed to retrofit or complement existing Siemens lighting solutions, this module provides a low-profile indicator that fits standard 30 mm openings, enabling quick field replacement and consistent visibility in control-room or equipment enclosures.
