Siemens 52PA4P4 Pilot Light

Siemens 52PA4P4 is a 30 mm illuminated pilot light in Siemens' 52-series Pilot Devices family, engineered to mount with Siemens 52-series pushbutton units to provide a clear control-panel status indication. This heavy-duty indicator serves to show equipment operating state or fault conditions in industrial panels and is designed for panel mounting in compatible enclosures. The pilot light supports a broad operating voltage range, typically 24 to 240 VAC or DC, with variants offered for higher voltage applications (including 277 VAC in some configurations). Lens colors in the 52PA4 family commonly include red, green, and amber, and available legends cover ON, RUN, OFF, and TRIPPED, though the exact combination is determined by the specific model configuration. Installation aligns with Siemens’ recommended practices for the 52 family, including mounting in NEMA Type 1 clamshell enclosures, and the broader Siemens catalog notes compatibility with NEMA 4 plastic or non-corrosive enclosures where applicable. The 52PA4 line is part of the broader set of 52PA4, 52PC4, 52PE4, 52PX4, and 52PY4 pilot-light variants, enabling a range of color/legend and voltage configurations to suit different control schemes. For the precise features of 52PA4P4, including the exact lens color, legend, and voltage rating, refer to the specific product listing from Siemens or authorized distributors.
