521746-1

TE Connectivity AMP Connectors introduces the 521746-1, a breakthrough in Terminals - Housings, Boots technology for renewable energy systems. This environmentally resistant solution optimizes power transmission efficiency while withstanding extreme weather conditions.The Housing architecture features integrated cooling fins for natural convection heat dissipation. The UV-stabilized copolymer housing resists degradation from prolonged solar exposure.Designed for Quick Connect, Disconnect photovoltaic applications, these contacts utilize silver-tin oxide plating for DC arc suppression. The multi-point contact design maintains <1mV drop at 30A continuous current.With Female, Receptacle configuration, this waterproof interface meets IP68 submersible standards. The self-sealing gasket system prevents moisture ingress in coastal installations.Precision-engineered to 0.250" (6.35mm) specifications, these terminals accommodate 10AWG to 14AWG conductor ranges. The anti-corrosion plating withstands acidic rain exposure.The 9 parallel configuration supports string monitoring with isolated voltage sensing. Each channel features Type II surge protection per IEC 61643-11.Featuring Top to Bottom flexibility, this design enables vertical or horizontal array configurations. The polarized interconnects prevent reverse polarity during system expansion.Validated for 0.250" (6.35mm) Quick Connects integration, this solution maintains stable contact resistance through 200+ thermal cycles. The halogen-free materials meet RoHS 3 compliance.The Free Hanging (In-Line) system allows both rail and pole mounting configurations. The integrated torque limiter prevents over-tightening during field installation.The Blue housing provides 70% solar reflectance to reduce thermal buildup. The non-glare surface finish minimizes visual pollution in residential installations.
