Flameproof Plugs & Sockets

Product Details:

SAIEX Flameproof Plug and Socket is a specialized heavy-duty electrical connector designed for use in hazardous environments where flammable gases, vapors, or dust are present. Unlike standard household plugs, these are engineered to contain any internal electrical spark or "arc" so that it cannot ignite the explosive atmosphere outside.

Other Names: Explosion Proof Plug and Socket, Flameproof Electrical Connector, Ex Proof Plug and Socket, ATEX Plug and Socket, IECEx Plug and Socket, Hazardous Area Plug and Socket, Industrial Explosion-Protected Connector, Gas-Tight Plug and Socket, Zone-rated Plug and Socket

Amperes: 16Amp, 25Amp, 32 Amp

Plug & Socket: 3 Pin, 4 Pin, 5Pin

CERTIFICATES: 

·         BIS

·         CIMFR

·         PESO

STANDARDS:

IS/lEC 60079-0:2017 | Explosive Atmosphere- Part 0: General requirements.

IS/lEC 60079-1:2014| Explosive Atmosphere- Part 1: Equipment Protection by Flameproof enclosures “d”

IS/lEC 60019-31:2013| Explosive Atmosphere- Part 31: Equipment Dust ignition protection by enclosure “t”

APPLICATION:

Key Design Features:

• Heavy-duty metal enclosure (aluminum / stainless steel / brass)
• Flame paths that cool hot gases
• Interlock mechanism (plug cannot be removed under load)
• High ingress protection (IP65 / IP66 / IP67)
• Earthing continuity before live connection

Operating Principle:

1.      Power is OFF before insertion/removal

2.      Plug is inserted into socket

3.      Mechanical interlock allows power ON

4.      Any spark remains sealed inside the enclosure

5.      Plug removal automatically cuts power first

Common Applications

·         Portable motors and pumps

·         Welding machines

·         Temporary lighting

·         Mobile tools and equipment

·         Maintenance power supply in hazardous areas

·         Shipyards and offshore platforms

Oil & Gas: Refineries, offshore drilling rigs, and fuel pumping stations.

Chemical Plants: Areas where volatile solvents or fertilizers are processed.

Mining: Underground coal mines where methane gas (firedamp) or coal dust accumulates.

Paint & Ink: Spray booths and mixing rooms with high concentrations of flammable fumes.

Grain & Flour: Silos and mills where fine organic dust is highly combustible.

Pharmaceuticals: Labs and production lines using alcohol-based chemicals.

Product Details:

“SAIEX” Flameproof Plug & Socket is a heavy-duty electrical connector designed for use in hazardous (explosive) atmospheres where flammable gases or vapors may be present.

Its purpose is to:

• Allow safe connection and disconnection of electrical equipment
• Contain sparks or arcs produced during plugging or unplugging
• Prevent ignition of the surrounding hazardous atmosphere

Flameproof means the enclosure can withstand and contain an internal explosion and cool escaping gases so they cannot ignite the external environment.

Various Names (Equivalent Terms): Flameproof Plug & Socket, Explosion-Proof Plug & Socket, Ex d Plug & Socket, Hazardous Area Plug & Socket, ATEX Plug & Socket, IECEx Plug & Socket, Industrial Flameproof Connector, EEx d Plug & Socket (older IEC terminology)

Gas Group: IIC, Temperature class: T6, Zone: 1/2 & 21/22

IP Protection: IP 66 as per IS/IEC 60529: 2001

Colour: Epoxy Grey 631 (Other option Pebble Grey 7032, 7035 & Pure White 9010 if the MOQ is more than 1000 nos)

Gasket: Endless Molded Neoprene (‘O’ Ring)

MOC: Cast Aluminium Alloy LM-6

Earthing: 1 nos inside & 2 nos Outside

Electrical Maximum Rating: 32 Amp, 24V DC/240V AC/415V AC

Marking Plate: (Ex db IIC T6 Gb) (Ex tb IIIC T85^o C Db)

Amperes: 16Amp, 25Amp, 32 Amp

Plug & Socket: 3 Pin, 4 Pin, 5Pin

Cable Entry Size: M20

Cable Entry Nos: 1 or 2 nos

Accessories: With or Without Cable Gland

For Regular and Clean Room Fittings

CERTIFICATES: BIS | CIMFR | PESO

STANDARDS: IS/lEC 60079-0:2017 | IS/lEC 60079-1:2014| IS/lEC 60019-31:2013

How It Works

Construction Features

• Robust metal or reinforced polymer enclosure (aluminum alloy / stainless steel)
• Precisely machined flame paths
• Interlocking mechanism (prevents live plugging/unplugging)
• Spring-loaded contacts
• Explosion-proof cable glands (Ex d)
• High Ingress Protection (IP65 / IP66 / IP67)

Working Principle

1. Power is supplied to the socket.
2. The plug is inserted and locked into position.
3. Interlock mechanism ensures:
   • Power is ON only after full engagement
   • Power is OFF before withdrawal
4. During connection/disconnection:
   • Any spark or arc occurs inside the flameproof enclosure
5. If ignition occurs:
   • Enclosure contains the explosion
   • Flame paths cool escaping gases
   • External hazardous atmosphere remains safe

Where Are Flameproof Plug & Socket Used?

Used wherever portable or fixed electrical equipment must be safely connected in explosive environments.

Common Industries

• Oil & Gas (onshore & offshore)
• Petrochemical plants
• Chemical industries
• Refineries
• Power plants
• Paint and coating facilities
• Mining
• Fertilizer plants
• Pharmaceutical solvent areas

Typical Applications

• Portable pumps
• Welding machines
• Hand tools
• Temporary lighting
• Heaters
• Mobile compressors
• Maintenance equipment
• Test instruments
