Explosion Proof Boxes
Explosion Proof Box, SUREALL Low-voltage Control Guide
Driving the state of the art innovation for power distribution and control for electrical equipment in harsh and hazardous location
Explosion proof box, also called explosion proof boxes, include but not limit to explosion proof electrical box, explosion proof switch, explosion proof light switch, flameproof on off switch, limit switch explosion proof, explosion proof junction box, stainless steel junction box, ex proof junction box, explosion proof panel, explosion proof panelboards, class 1 div 2 miniature circuit breaker, explosion proof enclosure, class 1 div 1 enclosure, ex enclosures, hazardous location enclosure, explosion proof receptacle, explosion proof plug, explosion proof socket, explosion proof plug and socket, explosion proof outlet.
The function of flameproof boxdepend on the electrical components installed such as switch, terminal blocks, circuit breaker, buttons, indicators, plug-in contact. The safety of all electrical components are enhanced in advance and protected by flame proof aluminum alloy housing, increased safety glass reinforced plastic housing or stainless steel housing, thus any electrical arcing can be confined to prevent the explosion from conveying to outer explosive atmosphere where flammable gas, vapor or dust present. They can be used in harsh and hazardous location whose optional hazard class division can be class 1 div 1, class 1 div 2, class 2 division 1, class 2 division 2, gas group A, B, C, D, gas group C, D, dust group E, F, G, zone 1, zone 2, zone 21, zone 22, gas group IIB, gas group IIC, dust group IIIC.
What Is An Explosion Proof Junction Box?
In the narrow sense, exd boxmeans connection box are equipped with terminal blocks for branch circuit cables. Whereas, in the broad sense, explosion proof junction box means explosion proof box with many kinds of electrical components during all electrical control process from field bus to loads, explosion proof box function as explosion proof switch with built-in switch to control the power on and off for explosion proof lighting, explosion proof box function as explosion proof panel with built-in circuit breakers to distribute feeder electricity from main circuits to brand circuits, explosion proof boxes and fittingsfunction as explosion proof enclosure with built-in other control devices to act certain functions , explosion proof box function as explosion proof receptacle with built-in plug-in contact through plug to connect and disconnect the power for explosion proof lighting and loads.
As for the principle to make the box explosion proof, SUREALL mainly apply for two methods, one is flame proof, the other is increased safety, you know flame proof means we put all electrical devices in the high resistance aluminum alloy housing, this housing isolate the ignition to make the explosion happen in the outer environment in hazardous location. Increased safety means all material of electrical device are made of high quality and performance metal and plastic to limit the electrical arcing exactly inside the housing without leakage.
Now we are listing some widely used actual explosion proof technology for explosion proof box as below:
> What is Ex d box?
Ex d box means the box set only have one or several sets of flame proof(Ex d) aluminum alloy housing, you can put general(non-hazardous) electrical components inside to make it explosion proof, it is widely used for simple control units in hazardous location. In case you need to install operating handle(normally buttons, switches, indicators) to control the power on and off for built-in components on the housing cover surface, the thread of handle and c hubs on the housing cover should be flame proof(Ex d).
What is Ex d box?
There are two types Ex de box as below:
Ex de box means the box set only have one or several sets of flame proof aluminum alloy housing, you can put increased safety(Ex e) electrical components inside to make it explosion proof, this kind of combination for flame proof(Ex d) housing and increased safety(Ex e) electrical components conclude Ex de box, it is widely used for complicated control units in hazardous location.
Ex de box also means the box set do not only have at least one set of flame proof(Ex d) aluminum alloy housing with increased safety(Ex e) electrical components, but also at least one set of increased safety(Ex e) housing (normally glass reinforced plastic or stainless steel material) with built-in increased safety(Ex e) components(normally terminal blocks), this kind of combination for flame proof(Ex d) housing and increased safety(Ex e) housing conclude Ex de box, it is widely used for extra complicated control units in hazardous location.
What is Ex de box?
Ex ed box means the box set have only one or several sets of increased safety(Ex e) housing (normally glass reinforced plastic or stainless steel material), you can put flame proof(Ex d) electrical components inside the housing, this kind of combination for increased safety(Ex e) housing and flame proof(Ex d) electrical components conclude Ex ed box, it is widely used for complicated control units in hazardous location and high corrosive environment.
