Hoạt độngATEX Green Push Button GRP Enclosure
Pepperl+Fuchs ATEX-certified green push button in GRP (fiberglass) enclosure for Zone 1.
Ứng Dụng Phổ Biến
Purpose-built for hazardous area installations where the entire button assembly must be explosion-proof. The GRP (glass-reinforced polyester) enclosure is corrosion-resistant and lighter than cast aluminum — preferred on offshore oil platforms where weight and salt spray are concerns.
Thông số kỹ thuật
|
ATEX Zone
The hazardous area classification. Zone 1 = gas likely present. Zone 2 = gas unlikely. Zone 21/22 = combustible dust.
|
Zone 1, Zone 2
|
|
Certifications
Third-party safety certifications. UL = required for US NEC installations. CE = EU compliance. CSA = Canadian standards.
|
ATEX, IECEx
|
|
Color
Button/actuator color. Green = start/go, Red = stop/emergency, Yellow = caution, Blue = reset (per IEC 60204-1).
|
Green
|
|
Contact Configuration
Normally Open — circuit is off until you press. Standard for start/go/enable functions.

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

Explosion Group
The gas group the device is certified for. IIC covers hydrogen (most restrictive). IIB covers ethylene. IIA covers propane.

IP Rating
IP66: Dust-tight and withstands powerful water jets from any direction. Standard for outdoor and washdown applications.

Hướng Dẫn Cài Đặt Nhanh
Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).
Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

Sơ đồ đấu dây
Khắc phục sự cố
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.

Những Đánh Giá Từ Khách Hàng
“Make sure you get Zone 1 rated, not just Zone 2. The Schneider XB4 ATEX range is solid but the Pepperl+Fuchs units with GRP enclosures are better for offshore where salt spray is a factor.”
