The nuts and bolts of any electrical system are the connectors which keep the current flowing. Blue Sea Systems connectors reduce heat and improve efficiency and reliability in a boat's electrical system. The features below make Blue Sea Systems connectors stand out from the others.
Tin plated copper bus provides maximum conductivity and corrosion resistance
Insert molded stainless steel studseliminates the need fro securing nut and allows high torquing for excellent electrical contact.
UL 94-40 rated base material resists high heat.
Stainless steel split ring lock washers and captive star-type lock washers keep connections tight in high vibration environments.
Optional insulating covers meet ABYC and USCG insulation requirements.
