Schneider Electric XA2EVB4LC XA2E red LED pilot light 24 V

XA2EVB4LC: XA2E red LED pilot light, 22 mm, 24 V AC/DC

The XA2EVB4LC is a Schneider Electric Harmony XA2 monolithic pilot light with a red 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 XA2EVB4LC 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.

Technical specifications of the XA2EVB4LC

LED light source and supply of the XA2EVB4LC

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.

Lens colour and signalling role of the XA2EVB4LC

Red normally signals danger, a fault or an alarm that needs immediate action, so it belongs on trip, fault and emergency indications rather than on routine running lamps. A pilot light is only as clear as its label, so engrave or mount a legend plate beside the XA2EVB4LC 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.

Mounting and wiring of the XA2EVB4LC

The pilot light mounts in a hole of 22.5 mm ± 0.2, secured by a nut beneath the head with a recommended torque of 2.2 N.m (± 0.2 N.m). The panel can be metal 1–6 mm thick or plastic 2–6 mm thick, with at least 30 x 40 mm of support area. The unit is 29 mm wide, 29 mm high and 53 mm deep and weighs 0.02 kg.

Wiring uses screw clamp terminals for up to 2 x 1.5 mm² with cable end or 1 x 0.5–2.5 mm² without, tightened to 0.8–1 N.m. The screw heads accept a No 2 Philips driver or a flat 4 mm or 5.5 mm blade.

Environment, packaging and approvals for the XA2EVB4LC

The front is rated IP65 with impact rating IK05. Operation is specified from -25–70 °C and storage from -40–70 °C. Vibration resistance is 5 gn (f= 12…500 Hz) and shock resistance 30 gn (duration = 11 ms). Marking is CE and CCC and the standards named are IEC 60947-5-1; GB 14048.5; GB 14048.1; IEC 60947-1; IEC 60529; IEC 50102.

The datasheet also states EU RoHS compliance and a recyclability potential of 20 %.

Where the XA2EVB4LC 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 red 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.
