Schneider Electric XA2EVB3LC XA2E green LED pilot light 24 V

XA2EVB3LC: XA2E green LED pilot light, 22 mm, 24 V AC/DC

The XA2EVB3LC is a Schneider Electric Harmony XA2 monolithic pilot light with a green round lens and an integral clustered LED, powered from 24 V AC/DC. It fits a 22 mm panel hole and is supplied without a replaceable bulb, because the light source is part of the unit. Seven Star LLC supplies the XA2EVB3LC in Oman and the GCC as an independent supplier in Muscat.

No lifecycle notice appears on the datasheet used for this page, which is dated 8 Nov 2026. The reference decodes from its product title: colour, supply voltage and the LED light source.

LED light source and supply of the XA2EVB3LC

The datasheet lists a COB clustered LED, no bulb base, steady signalling and a rated supply voltage of 24 V AC/DC. Current consumption is at most 20 mA, and the service life is given as 40000 h at rated voltage and 25 °C. At that service life, the lamp is effectively a fit-and-forget part, but the figure assumes rated voltage and moderate temperature.

Because the supply is 24 V AC/DC, the same lamp works on a DC control bus or an AC control transformer, which simplifies stocking. At 24 V this is the low-voltage version, normally fed from the control supply of a PLC panel. The terminals are marked as shown in the datasheet (X1-X2) and polarity does not need to be observed on AC.

Technical specifications of the XA2EVB3LC

Lens colour and signalling role of the XA2EVB3LC

Green normally signals that equipment is running or in a normal, safe condition, so this lens suits run, ready and healthy-supply indications. A pilot light is only as clear as its label, so engrave or mount a legend plate beside this unit that states exactly what the lamp indicates.

Keep one meaning per colour across the whole panel and across sister panels at the site, so that operators on different shifts read the lamps the same way. If two lamps of the same colour mean different things, a distinguishing legend is essential.

The XA2EVB3LC among XA2E pilot lights

The six pilot lights in this range of references share one body and LED source. They differ only in lens colour and supply voltage.

Choose the colour for the meaning you need and the voltage to match the panel control supply.

Where the XA2EVB3LC is used in Oman and the GCC

Pilot lights of this type show status on motor control centres, pump and compressor panels, generator controls, water and wastewater stations and building services boards. A green lamp such as this unit is typically wired to a contactor auxiliary contact, a PLC output or a relay contact so it follows a machine state.

In bright sun or strongly lit control rooms, an LED lens is easier to read than an old filament lamp, and with no bulb to replace the maintenance task disappears. Dust and heat still apply: keep the front clean and make sure the enclosure interior stays within the operating range.

Installation and replacement notes for the XA2EVB3LC

Before fitting, check that the supply is 24 V AC/DC and that it is a steady rather than a flashing signal, since the datasheet lists steady signalling only. Fit the unit in the panel hole, tighten the nut to the recommended torque and connect the two terminals; no polarity is needed on AC.

When replacing a failed lamp, match colour, voltage and size. Do not mix a 24 V and a 110 V version in the same panel row without clear marking, as the lenses look identical. Test with a lamp-test button or by briefly energising the circuit and record the reference this unit in the panel drawing.
