Schneider XB4 red pilot light for 230V AC.
常见应用
Red 230V indicator for European direct-mains panels. Fault indication on 230V circuits.
Research Notes
1. Overview
The Schneider Electric XB4BVB4 is a complete 22 mm Harmony XB4 red pilot (indicator) light — a metal (chrome) bezel, flush, illuminated status light (not a pushbutton) with a plain lens and an integral 24 V AC/DC LED. It's an all-in-one assembled unit for showing machine/process status; red conventionally signals fault / stop / danger / abnormal. (Data-quality note: this was cataloged as "230 V AC" (PN "XB4-BVB4-230") — per Schneider it is 24 V AC/DC. In the XB4-BV code the voltage letter B = 24 V (G = 110–120 V, M = 230–240 V); the "-230" suffix is incorrect. Color 4 = red is correct.)
2. User Sentiment
The Harmony XB4 metal line is an industry standard — robust chrome-bezel construction, big modular ecosystem, broad stock. As a complete pilot light it's convenient to order/install. The key care point (and this entry's error) is matching the LED voltage correctly — decode the XB4-BV voltage letter rather than trusting an appended "-230".
3. Real-World Applications
Panel/machine status indication — red lit lens for fault/stop/danger/abnormal conditions on a 24 V AC/DC supply, alongside XB4 pushbuttons and other indicators.
4. Technical Specifications
- Type: Harmony XB4 complete pilot (indicator) light, 22 mm — not a pushbutton
- Bezel/material: metal (chrome)
- Lens: plain, red, flush
- Illumination: integral LED, 24 V AC/DC
- Cutout: 22 mm
- Sealing: IP66 / IP69K
- Approvals: UL, CSA, CE
5. Ordering & Compatibility
Complete unit — no separate head/LED ordering. Fits 22 mm cutouts. XB4-BV code: voltage letter B = 24 V, G = 110–120 V, M = 230–240 V; color digit 1 white / 3 green / 4 red / 5 yellow / 6 blue. Confirm the 24 V supply for this part.
6. Known Issues / DQ
- DQ: it's 24 V AC/DC, not 230 V (color red is correct). Corrected here (the "-230" PN suffix is bogus — same pattern as XB4BVG6 #485).
- Practical care: match the LED voltage (24 V here) and confirm the 22 mm cutout; it's a pilot light (status), not a pushbutton.

Corrected: XB4BVB4 = red, 24V AC/DC (se.com). Was mislabeled 230V (bogus -230 suffix). XB4-BV voltage letter B=24V (G=110-120V, M=230-240V). AUDIT other XB4-BV*-230 entries.

安装快速参考
Panel cutout: 22mm. Insert from the front, secure with mounting nut.
LED module: Check the voltage rating matches your supply (typically 24V DC or 230V AC). Connect to PLC digital output or relay contact for status indication.
Color meaning (IEC 60204-1): Green = normal/running. Red = fault/danger. Yellow = warning/caution. Blue = mandatory action. White = neutral/general.

故障排除
Light is dim or flickering
Check supply voltage matches the LED module rating. Low voltage causes dimming. If voltage is correct, the LED module is failing — replace it. LED modules have finite life (typically 50K-100K hours).
Light doesn't turn on
Verify voltage at the terminals with a multimeter. Check the PLC output or relay driving the light. LED modules are polarity-sensitive on DC circuits — try reversing the leads.
