Siemens 52BL4G3XB Pilot Light LED Module Transformer

Siemens 52BL4G3XB Pilot Light LED Module Transformer is a complete 30 mm panel-mount indicator that pairs a green LED pilot lamp with an integrated transformer for 120 VAC input. Housed in a durable BlackMax epoxy-coated metal enclosure, it uses a BA9s plastic lens and a concentric-ring lens design to deliver bright visibility. The internal transformer supplies 6 V AC/DC to the LED module, enabling low-voltage LED operation from a standard 120 VAC circuit. Designed for harsh control panels, the unit is rated for multiple NEMA enclosures: 1, 3, 3R, 4, 4X, 12, 13, and carries UL Listed and CSA Certified marks. Terminals are screw-type for straightforward wiring and service. As part of Siemens’ 52BL LED pilot-light family, 52BL4G3XB provides green illumination and is intended for equipment status indication on industrial machines, conveyors, and panel boards where a compact, transformer-powered indicator is required. This model’s combination of transformer-powered LED illumination, 30 mm footprint, and robust construction makes it a reliable choice for Siemens automation installations and compatible control panels requiring a 120 VAC input with a green LED indicator.
