The Powertite explosion-proof plug and receptacle and the explosion-proof EBR receptacle are now available in 150-A versions. Said to be the first of their kind, the upgrades are intended to fulfill the need to supply power over long runs to industrial equipment rated at around 100 A. This eliminates the risk of overdriving or drawing excessive current beyond the maximum continuous rating on a piece of equipment, which can lead to additional maintenance costs.

Other upgraded features include arc-snuffing chambers, multiple grounding styles and positive polarization to prevent dangerous matching of dissimilar amperages. The plugs and receptacles are UL Listed, CSA Certified and rated NEMA 4X. They are approved for use in Class 1, Div 1 and 2 hazardous locations, such as petrochemical plants, petroleum refineries, paint and chemical factories and other areas where ignitable vapors or gases are present.
