Low current switch to control the power on and off for explosion proof

lighting and device for explosive atmosphere

Explosion proof switch, other names saying explosion proof light switch, flame proof on off switch, explosion proof pressure switch, explosion proof disconnect switch, explosion proof disconnect, limit switch explosion proof, ex proof push button, hazardous location disconnect switch, anti spark power switch, zone 2 light switch, division 2 for switch, explosion proof level switch, explosion proof key switch, explosion proof proximity switch, class 1 switch, explosion proof e stop, spark proof switches, explosion proof switch box, explosion switch, square d explosion proof disconnect switch.

Protected by flame proof housing or increased safety electrical parts, explosion proof switch is a common usage for end-to-end control unit to control the power on and off for explosion proof lighting whose low current is normally not more than 32 ampere in hazardous location. The housing of explosion proof light fixture switch ranges from die cast aluminum alloy for most case and glass reinforced plastic for extreme corrosive case. No matter it shapes like on-off switch or button, explosion proof switch is a small size switch playing the same functions in real applications, you should select explosion proof panel if you intend to control the high current electrical equipment such as motor starter whose working current can be more than 32 ampere.

Function

After installing any explosion proof lighting, you need install explosion proof switch to control the power on and off of explosion proof lighting in order to manager when and how to lighten for any place at dark time or night to run the projects constantly even with 24 hours.

Hazard class division

You know there are different classifications and divisions for explosion proof switch, hazard class division can be class 1 div 1 and class div 2, class 2 division 1 and class 2 division 2, zone 1 and zone 2, zone 21 and zone 22, you can check the hazardous area classifications chart from other pages.

Usage by application

Depends on the application field, explosion proof switch can be used in where explosion proof lighting installed, such as oil extraction plant, oil or gas refinery plant, oil processing plant, petrochemical and chemical plant anywhere there is combustible gas, vapor, mist and dust.

Alternative for brand-new model

SUREALL explosion switch is the alternative light switch solution for bzm, deds, eds switch, efd switch, explosion proof button, explosion proof emergency stop station, atex push button, flame proof switch gear, division switch, class 1 div 2 switch, class 1 division 2 switch, explosion proof selector switch.

What is Explosion Proof Switch?
SW-A series and SW-P series explosion proof switch can be used in class 1 div 1 and class 1 div 2. SUREALL explosion proof switch SW-A Series put a switch in an enclosed aluminum housing prevent the combustible gas or vapor from entering into the internal of housing to reduce the possibility for explosion, in case flammable gas or vapor is ignited, the housing can prevent the explosion heat from running to external environment to cause explosion outside of the housing to ensure the safety. Explosion proof switch SW-P series is protected by a factory sealed glass reinforced plastic housing to block the entering gap of hazardous atmosphere, at the same time, the safety of electrical circuit material inside are enhanced in advance to decrease the arcing.

FAQs about Explosion Proof Switch
Q
How are explosion-proof switches different from standard duty switches?
A
Standard duty switches probably produce electrical arcing when short-circuit or incorrect operation which are widely used in residential electrical application, but SUREALL explosion proof switches SW-A and SW-P series can protect the electrical arcing in enclosed explosion proof housing to avoid explosion where combustible substance present.

Q
What is a Class 1 switch?
A
Class 1 switch is explosion proof switch used in flammable gas environment such as acetylene, hydrogen, ethylene, propane. Class I mean hazardous gas group subject to NEC500 standard, SUREALL explosion proof switch SW-A and SW-P series are all class 1 switch.

What is EDS controls?
A
EDS controls means Ex d switch, also called explosion proof switch, which are constrained by flame proof aluminum alloy enclosure to reduce the explosion possibility when electrical spark ignite the explosive gas or dust in hazardous location, you can check the specification page from SUREALL SW-A series for details.

Q
Is Cast Aluminum flameproof?
A
Only part of cast aluminum is flame proof, the material cast aluminum itself is not flame proof, when the cast aluminum housing can resist the explosion pressure without damage and is designed with accurate calculated flame path, SUREALL SW-A series can be flame proof.

Q
What are snap switch
A
Snap switch is made of two or more metal conductor contacts seated on the insulating base, after soft mechanical flipping, the contacts are toughed and connected to control the switch on and off. SUREALL put the snap switch inside the explosion proof housing and design an outer handle on the housing cover for convenient operation.
