Weg (Marathon) Flameproof Motor IE2 & IE3
Overview
An explosive atmosphere is one where a mixture with air under atmospheric conditions of flammable substances in the form of gas, vapor, or mist exists in such a proportion that it may explode due to excessive temperature, arcs, or sparks. Flameproof motors are manufactured with an enclosure constructed in such a manner that any explosion inside is not capable of igniting an explosive atmosphere outside the enclosure, and the surface temperature is safe enough not to ignite the outside explosive atmosphere.
