SIEMENS 30 mm Red Pilot Light
This 30 mm round pilot light from SIEMENS provides a red LED indication for 480 V AC control circuits. It uses a transformer-type lamp module that steps the supply down to a 6 V AC/DC LED, and it mounts via screw terminals in a metal body with a plastic concentric-ring lens.
NEMA 1 12 13 3 3R 4 4X IP20 IP66 Rating
The enclosure carries NEMA ratings 1, 12, 13, 3, 3R, 4 and 4X together with IP20 and IP66 protection, so the unit resists dust, water jets and temporary submersion in normal industrial environments. No active cooling is required, and the LED lamp produces negligible heat and no audible noise during standard operation.
Continuous 480 V AC Duty With Transformer Module
Under sustained load the transformer module maintains the LED at its rated 6 V without flicker or colour shift, and the epoxy base material withstands prolonged thermal cycling. The lamp module is not field-replaceable, so buyers who need a user-serviceable lamp should consider a different indicator style.

Questions about this item
How do I wire the screw terminals on this 480V AC pilot light?
Connect the supply wires to the screw terminals on the lamp module; the unit operates at 480V AC with an internal transformer supplying 6V AC/DC to the LED, so ensure the circuit is de-energised before tightening connections.
What parts will need replacement over time on this 30mm LED indicator?
The LED lamp module is integrated and replacement lamps are listed as N/A, so the entire pilot light assembly would be replaced if the light output degrades.
At what temperature or duty cycle does the NEMA 4X and IP66 sealing become the limiting factor?
The housing is rated NEMA 1, 3, 3R, 4, 4X, 12, 13 and IP20, IP66 for dust and water ingress; sustained operation at the rated 480V AC within these environmental limits is the design intent.
