ARK-trol® RPC and RPE Series Special Purpose Power Connectors


ARK-trol® RPC and RPE Connectors are used:

  • For connection of devices ranging from lighting units and power tools requiring only a power supply circuit, to sophisticated control and instrumentation assemblies requiring disconnect
  • Where exposed to dust, dirt, water, corrosion and chemical attack
  • In non-hazardous areas of refineries, chemical and petrochemical plants, and military installations

  • All ARK-trol® plug, receptacle and cord connector shell parts are of high-strength impact extruded aluminum, hard coated with a high density anodize finish; the resultant assemblies are lightweight, extremely strong, free from surface defects and flaws, and with superior resistance to abrasion, corrosion and chemical attack
  • Polarization of ARK-trol® connectors is such that plugs and receptacles cannot be mated incorrectly
  • Shell components and insert assemblies in each diameter are interchangeable; both male and female basic shells will accept either pin or socket inserts; this feature permits the use of both plug and receptacle in either an energized or deenergized condition
  • Grounding socket contacts are longer than current carrying contacts to make first and break last, assuring a positive ground before circuits are energized and after circuits are de-energized
