Product details
Würth Elektronik's 691321300008 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 Header, Male Pins, Shrouded (4 Side) 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 8 positions, the design supports both string and combiner box configurations. The parallel contact arrangement minimizes power loss in high-current PV applications.With 8 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.Vertical options facilitate installation in various enclosure types. The right-angle versions minimize wire bending in compact combiner boxes.The Solder technology ensures reliable connections in vibrating wind turbine nacelles. The corrosion-resistant materials withstand salt spray and industrial atmospheres.Through Hole installation satisfies both rail and direct mounting requirements. The universal design simplifies maintenance in hard-to-access locations.Rated for 10 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.The Green housing incorporates solar industry-standard color coding. The high-reflectivity surface reduces heat absorption in direct sunlight.Operating across -40°C ~ 105°C range, the materials withstand desert heat and arctic cold. Accelerated aging tests confirm 25-year service life in outdoor conditions.Tin plating provides optimal performance for renewable energy applications. The selective gold plating on critical surfaces prevents fretting corrosion.
