Product details
Phoenix Contact's 1857951 establishes new standards in Terminal Blocks - Headers, Plugs and Sockets for renewable energy systems. This innovative interconnect solution is specifically developed for solar and wind power applications, combining high-voltage capability with environmental resistance. The Terminal Blocks - Headers, Plugs and Sockets delivers reliable performance in utility-scale renewable energy installations.The Plug, Male Pins architecture incorporates UV-resistant materials for outdoor installations. Compared to standard components, it provides 50% better weather resistance in desert and coastal environments.Available in 9 positions, the design supports both string and combiner box configurations. The parallel contact arrangement minimizes power loss in high-current PV applications.With 9 positions per level, the layout optimizes heat dissipation in enclosed junction boxes. The thermal modeling confirms 15 C lower operating temperatures than conventional designs.The 1 stacking capability enables vertical expansion in combiner boxes. This approach maintains proper creepage distances while maximizing space utilization.Featuring 0.150" (3.81mm) pitch spacing, the design exceeds IEC 61730 requirements for PV systems. The reinforced isolation barriers prevent DC arcing in high-voltage arrays.Engineered with 180° entry options, the system accommodates both top and side cable entry. The weatherproof strain relief prevents moisture ingress in outdoor installations.The Screw - Rising Cage Clamp technology ensures reliable connections in vibrating wind turbine nacelles. The corrosion-resistant materials withstand salt spray and industrial atmospheres.Free Hanging (In-Line) installation satisfies both rail and direct mounting requirements. The universal design simplifies maintenance in hard-to-access locations.Meeting 8A IEC standards, the design handles reverse current flow during fault conditions. The robust construction withstands short-circuit forces without deformation.The 320 V certification includes testing for altitude derating. The design maintains performance at 3000m elevation without reduction in voltage rating.Rated for 8 A continuous current, the contacts utilize silver-nickel alloys. This material combination minimizes resistance rise during thermal cycling.The 300 V rating includes design margin for voltage spikes in PV systems. The insulation system withstands 2000V DC without degradation.Compatible with 14-30 AWG PV wire, the termination system includes integrated oxide-piercing features. This ensures low-resistance connections with aluminum conductors.The Green housing incorporates solar industry-standard color coding. The high-reflectivity surface reduces heat absorption in direct sunlight.Tin plating provides optimal performance for renewable energy applications. The selective gold plating on critical surfaces prevents fretting corrosion.
