Abstract
The present invention provides an electrical component enclosure for installation in a location where a flammable gas or vapor is expected to be present. The electrical component enclosure incorporates a catalyst for inducing a reaction to convert a flammable fluid to a non-flammable product, thereby reducing the flammable fluid concentration and reducing the likelihood of the flammable fluid being ignited. The enclosure preferably permits the free exchange of gas and vapor between the surrounding atmosphere and the enclosure interior.
