The Powertite® Series uses the versatile pin and sleeve design to provide safe, reliable power for any type of heavy duty equipment, fixed or portable. Available in 30, 60, 100, 150, 200 and 400 Amp designs, these plugs and receptacles are built of triple coated, copper free aluminum to withstand harsh weather, corrosive atmospheres and rough working conditions. Safety features include widely spaced contacts recessed within an internal arc snuffing chamber, insulating blocks, positive polarization and a durable neoprene bushing that seals out water and dust. Shell only or shell plus extra pole grounding designs provide safe, "make first, break last" grounding. Both standard and reverse service versions are available, and field conversion between the two is simple using a matching plug and receptacle for most styles. Appleton also offers a nonmetallic plug designed to work with Powertite® receptacles. Designed for easy installation, the Powertite® Series is Appleton's most versatile choice for standard and hazardous locations.
