Certifications and compliances

• Raintight

• 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

• 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
