ARK-trol heavy industrial special purpose power connectors

Crouse-Hinds series ARK-trol RPC and RPE heavy industrial special purpose power 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.

Ideal for use in non-hazardous areas of refineries, chemical and petrochemical plants, and military installations where connectors are exposed to dust, dirt, water, corrosion and chemicals.

Certifications and compliances

  • Raintight

Design features

  • All ARK-trol plug, receptacle and cord connector shell parts are of high strength impact extruded aluminium, hard coated with a high density anodised finish; the resultant assemblies are lightweight, extremely strong, free from surface defects and flaws, and with superior resistance to abrasion, corrosion and chemical attack
  • Polarisation 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 energised or de-energised condition
  • Grounding socket contacts are longer than current-carrying contacts to make first and break last, assuring a positive ground before circuits are energised and after circuits are de-energised

Standard materials

  • Back boxes and adaptors – copper-free aluminium
  • Plug, receptacle and cord connector shells – impact extruded aluminium
  • Insulation – fibreglass-reinforced polyester
  • Sealing wafer – silicone rubber
  • Contacts – hard drawn copper
