Schneider Electric **XB4BVB5EX** is a Harmony XB4 **22 mm complete pilot light** designed for reliable status indication on control panels and operator stations. It features a durable **chromium-plated metal bezel** with a **Zamak fixing collar**, a **plain round lens** in a yellow/amber indication colour, and an **integral LED** for steady signalling.
Designed for demanding industrial environments, it offers **IP65** ingress protection (also rated **NEMA 4X / NEMA 13**) and **IK05** impact resistance. The unit is intended for **24 V AC/DC (50/60 Hz)** operation with an operating voltage range of **19.2…30 V DC** or **21.6…26.4 V AC**, drawing **18 mA**. Connection is via **screw clamp terminals** accommodating **0.22…2.5 mm²** conductors (up to **2 x 1.5 mm²** with cable ends).
For installation, it suits a standard **22 mm mounting diameter** with a recommended **22.5 mm panel cut-out** (22.3 mm +0.4/0), a **43 mm embedding depth**, and **1–6 mm** panel thickness. The pilot light is marked **Ex tb IIIC** and specified for **ATEX dust zones 21–22**, making it suitable where dust-atmosphere equipment marking is required.

What is this device used for?
It is a complete 22 mm panel-mount pilot light used to provide a clear visual status indication on control panels and operator stations. It uses an integral LED and provides a steady (non-flashing) indication.
What mounting hole size is required for installation?
It is designed for a 22 mm mounting system with a recommended finished panel cut-out of 22.5 mm (acceptable tolerance is 22.3 mm with +0.4/0).
How much space is needed behind the panel?
Allow for an embedding depth of approximately 43 mm behind the panel for the body of the pilot light and wiring clearance.
What panel thickness can it be mounted on?
It is intended for support (panel) thicknesses from 1 mm to 6 mm.
What supply voltage does it require?
It is rated for 24 V AC/DC (50/60 Hz). Typical operating limits are 19.2 to 30 V DC and 21.6 to 26.4 V AC.
What is the current consumption?
Current consumption is approximately 18 mA at the rated supply voltage.
Does it have a replaceable lamp or an integrated light source?
The light source is an integral LED, meaning there is no separate lamp to fit. The rated service life is 100,000 hours at rated voltage and 25 °C.
What colour indication does it provide?
This model provides an amber/orange indication (often described as “yellow” in pilot light colour naming). It uses a plain lens and an orange/amber LED indication.
What ingress protection rating does it have?
It is rated IP65. It is also referenced with NEMA 13 and NEMA 4X performance ratings.
Is it suitable for dusty hazardous areas (ATEX dust)?
Yes. It is intended for ATEX dust environments and is specified for dust Zone 21–22 with marking Ex tb IIIC. If you need the exact marking on a listing, you can reference Schneider XB4BVB5EX.
What type of terminals does it use and what wire sizes can be connected?
It uses screw clamp terminals. Typical clamping capacities include up to 2 x 1.5 mm² when using cable ends, and 1 x 0.22 mm² to 2 x 2.5 mm² without cable ends (per IEC 60947-1 practices).
How robust is it against impact, vibration, and electrical disturbances?
It has IK05 impact resistance, vibration resistance of 5 gn (12…500 Hz), and shock resistance of 30 gn (18 ms) and 50 gn (11 ms). It also has surge withstand of 1 kV (IEC 61000-4-5) and fast transient immunity of 2 kV (IEC 61000-4-4).
What are the permitted ambient temperature ranges?
Typical ambient ranges are -20 °C to +60 °C during operation and -40 °C to +70 °C during storage.
What electrical ratings should be considered for insulation coordination?
Key insulation coordination values include a rated insulation voltage (Ui) of 250 V (pollution degree 3) and a rated impulse withstand voltage (Uimp) of 4 kV, in line with IEC 60947-1.
- Status indication on operator panels and control stations where a clear 24 V AC/DC pilot light is required
- Running/ready/fault signalling for motors, drives, pumps, fans, and general machine auxiliaries
- Alarm and attention indication on process skids, MCC panels, and local isolator enclosures
- Use on equipment installed in combustible dust environments (ATEX dust Zone 21/22), such as powder handling and conveying systems
- Machine state signalling on packaging, bottling, and materials handling lines using standard Ø22 mm panel cut-outs
- Visual confirmation of interlocks, permissives, and sequence steps in automated production cells
- Indication on washdown-prone or outdoor-mounted enclosures where an IP65 pilot light is preferred
- Panel-building applications needing a robust metal-bezel pilot light for frequent operator visibility in industrial environments
- Retrofit replacement for existing Ø22 mm pilot lights when standardising on integral LED indication at 24 V
- Local indication on hoppers, mixers, dosing systems, and extraction/filtration plant associated with dust-generating processes
