The Atex Push Buttons PB3 Series are rugged, flameproof control stations engineered for hazardous gas and dust zones where reliability and quick action matter. Each unit gives operators a clear, glove-friendly interface for start/stop, reset, selector, and emergency stop—right beside pumps, skids, conveyors, and valves. With corrosion-resistant housings, tight sealing, and Ex-compatible cable entries, PB3 stations perform day after day in the UAE’s heat, dust, humidity, and salt air across Dubai, Sharjah, and Abu Dhabi. If you want local controls that install fast, pass audits, and last for years, standardize on Flame proof Push Buttons in UAE – PB3 Series, supplied locally by Atex Hub.
Flameproof (Ex d) push buttons are sealed operator stations designed to contain any internal ignition and prevent it from igniting the surrounding atmosphere. The PB3 Series combines Ex d / Ex e / Ex t options with robust operators and high-quality contact blocks that control arcing and surface temperature. This lets you place control points close to the process—reducing walking time and improving response—while staying compliant. Built for the UAE, PB3 uses UV-stable materials, marine-grade hardware, and IP66/67 sealing, so legends remain readable, buttons stay smooth, and inspections stay simple in Dubai, Sharjah, and Abu Dhabi.
Start/Stop of motors, pumps, fans, and mixers
Emergency Stop (E-stop) for immediate safe shutdown
Reset/Acknowledge of alarms and interlocks
Mode selection (Hand/Off/Auto) via selector switches
Jog/Isolate functions during testing and maintenance
Oil & Gas / Petrochemicals: Pump skids, separators, compressor shelters, tank farms, chemical dosing panels
Marine & Ports: Pump rooms, jetties, deck machinery—areas with spray, vibration, and salt air
Utilities & Water: Chlorination rooms, MCC outstations, remote kiosks needing Ex-rated local control
Food, Pharma & Chemical: Powder and solvent zones requiring cleanable, clearly labelled stations
Industrial & Warehousing: HVAC, conveyors, mixers, and battery-charging areas in classified locations
Choose PB3 for simplicity, durability, and fast deployment. Enclosures in 316 stainless steel or GRP fight corrosion and UV. Metric and NPT entries match existing conduit; IP66/67 sealing keeps out dust and water. Inside, a clean layout speeds wiring and maintenance. With Atex Hub support, you get correct Ex markings, thread forms, dual-language legends, and drawings/nameplates tailored to UAE standards—so submittals move faster and audits go smoothly across Dubai, Sharjah, and Abu Dhabi.

1) What’s the difference between Ex d and Ex e?
Ex d contains internal ignition; Ex e avoids sparking through increased safety. Choose based on zone, gas group, and device type.
2) Can I include an Emergency Stop?
Yes—PB3 supports E-stop (mushroom, twist-to-release). Ensure contact ratings and the safety loop meet your risk assessment.
3) Do you provide Arabic/English legends?
Absolutely—dual-language legends and ISO/IEC symbols help pass UAE inspections and improve clarity.
4) What IP rating do I need outdoors?
Installed with Ex glands and sealing washers, PB3 achieves IP66/67. Re-torque and inspect seals during PM.
5) How many contacts can a station hold?
Most PB3 builds support up to four contact blocks (model dependent). Confirm I/O before ordering.
6) Are both metric and NPT threads available?
Yes—M20/M25 and ½″/¾″ NPT, plus certified reducers/adapters to maintain Ex/IP integrity.
