Frequent question: What does explosion proof motor mean?

Explosion proof motors are required for industrial applications with the presence of highly combustible, pervasive materials. … Rather, an explosion proof motor has features that prevent an internal motor explosion from igniting a larger, ambient, combustible atmosphere.

What are explosion proof motors used for?

In a Class I environment (UL designation), an explosion proof motor prevents an internal spark or flame from escaping the motor into the hazardous environment to ignite a flammable vapor or gas.

How do I know if my motor is explosion proof?

An electric motor is considered explosion-proof when it is capable of containing an internal explosion without rupturing and putting the entire industrial facility at risk.

What is meant by explosion proof?

Explosion proof, according to the National Electrical Code, applies to an apparatus enclosed in a case that is capable of withstanding a gas or vapor explosion. It means that, should there be an explosion, it will be contained within an enclosure.

Is a Class 1 Div 2 motor explosion proof?

While Division 1 motors in Class I locations must be explosion-proof, Class II, Division 1 motors must be dust- ignition-proof. … One important distinction is that the enclosure of a dust-ignition- proof motor is designed to exclude hazardous materials.

What makes a fan explosion proof?

Explosion-proof fans also use motors that are designed not to produce sparks as they cycle on and off. For added protection, the blades are often made of materials that won’t accumulate static electricity or otherwise become prone to sparking.

What is extrinsically safe?

Tag: extrinsically safe

Both approvals are meant to prevent a potential electrical equipment malfunction from initiating an explosion or ignition through gases that may be present in the surrounding area.

What is dust ignition proof?

Dust-ignition proof

A dust ignition proof component prevents dust entering from outside. Arcs, sparks and heat generated inside of the enclosure will not be able to ignite the exterior surroundings near the component.
