Dust wall switch is a switch device suitable for environments with dust. Dust explosion-proof wall switches can be used in hazardous areas where dust accumulates and may cause fire and explosion accidents, ensuring the on/off control of circuits, ensuring the normal operation of equipment, and avoiding safety accidents caused by sparks generated by switch operations. Widely used in production lines of industries such as coal, electricity, chemical, and metallurgy.

　　Precautions for use

potential safety hazard

Switches and sockets that are pressed down by flammable materials or dust falling in may cause short circuits. When installed in flammable and explosive hazardous areas, sparks may be generated when inserting or removing plugs, which may cause explosions and fires. At the same time, when combustible gases used in households mix with air to a certain limit due to leaks in channels or valves, electrical switches that do not eliminate arcing devices can generate sparks and cause fires or explosions.

maintenance

To ensure the stable operation of the dust wall switch, regular maintenance and upkeep are required. For equipment such as dust explosion-proof deviation switches EXZGLPT1/T2, their performance and operating conditions should be regularly checked.

　Selection of core performance requirements

Explosion proof certification

Choose products with national explosion-proof certification (such as ExmbIIICT6, ExdeIICT6, etc.) to ensure compliance with dust explosion-proof standards.

Priority should be given to selecting protection levels of IP66 or higher to ensure dust and water resistance.

Material and Structure

Shell material: The shell made of cast aluminum alloy has high sealing performance and can effectively block dust intrusion.

Internal design: Adopting an explosion-proof structure with built-in sealant treatment to prevent dust from contacting the circuit and causing short circuits or explosions.

Electrical parameter adaptation

Select the voltage (220V/380V) and current (10A-25A) range according to the usage scenario, and match the power requirements of the equipment
