IP44 Pin And Sleeve Devices Are Electrical Connectors For Use In Wet, Corrosive Or Hazardous Environments. Pin and Sleeve Devices feature solid brass pins for long lasting reliable electrical contact. Split contact sleeve with nickel plated steel springs provides optimum insertion/withdraw force. 3-Phase pin and sleeve devices are color coded in Blue or Red to provide positive voltage and frequency matching and eliminate installation errors. Max voltages available are 120/208, 230/250 and 400/480. Chamfered funnel entry terminals guide and capture all wire strands to protect against contact with live parts. Terminal identification (ground, neutral, phase) is clearly marked for safety. Poles are 2P+G, 3P+G or 3P+N+G. UL listed and CSA certified.
