Siemens 52PC4E9 is a 30 mm full‑voltage indicator light (pilot lamp) with an amber plastic lens, designed for 120 V AC/DC operation in Siemens’ 52 Class indicator family. The full‑voltage 120 V version uses an incandescent lamp rated at about 2.5 watts and is specified as 120 V AC/DC, amber in color, to provide bright, immediate visibility on panel assemblies. Built on Siemens’ watertight/oiltight Class 52 platform, this indicator light is intended for use inside control panels and enclosures—such as those meeting NEMA 4/12 protection requirements—where clear status indication is needed in industrial environments.
