XB4-BVB3
AtivoATEX Green Indicator Light 24V
Schneider Harmony XB4 ATEX-certified green pilot light for Zone 1/21 hazardous areas.
Aplicações comuns
Found on control panels in oil refineries, chemical processing plants, and offshore platforms. The ATEX Zone 1 certification means it can operate where explosive gas is likely present during normal operation. Green indicates process running or system OK.
Especificações

ATEX Zone
The hazardous area classification. Zone 1 = gas likely present. Zone 2 = gas unlikely. Zone 21/22 = combustible dust.
|
Zone 1, Zone 21
|
|
Certifications
Third-party safety certifications. UL = required for US NEC installations. CE = EU compliance. CSA = Canadian standards.
|
ATEX, IECEx, CE
|
|
Color
Button/actuator color. Green = start/go, Red = stop/emergency, Yellow = caution, Blue = reset (per IEC 60204-1).

Cutout Diameter
The hole size you drill in your panel to mount this button. 22mm is the most common industrial standard worldwide.
|
22mm

LED Voltage
The voltage required for the built-in LED. Must match your control circuit voltage (typically 24V DC or 230V AC).
|
24V AC/DC

Referência rápida de instalação
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.
Dimensões
Solução de problemas
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.
