744-392

The 744-392 from WAGO Corporation revolutionizes Terminal Blocks - Wire to Board technology for renewable energy systems. This high-efficiency terminal block is engineered specifically for solar inverters, wind turbine controls, and energy storage applications. The 510KBA-BAAG's innovative design withstands environmental extremes while maintaining optimal electrical performance in green energy installations.Featuring 1 isolated tiers, the block prevents DC arc propagation. The interlocking ceramic barriers withstand 1500V dielectric tests required for photovoltaic systems.The 2 configuration handles high-current busbar connections. Silver-plated contacts reduce power loss by 0.2% compared to standard tin-plated alternatives.0.138" (3.50mm) spacing prevents partial discharge in high-altitude installations. The optimized creepage distance meets IEC 60664-1 requirements for pollution degree 3 environments.Horizontal with Board installation accommodates outdoor enclosure designs. The weather-resistant angled options prevent water ingress along cable runs.Rated for 6 A continuous operation, the terminal block manages peak solar array outputs. The patented heat-sink design maintains temperatures 20 C below competitors' models at full load.The 300 V rating exceeds utility-scale renewable energy requirements. Triple-insulation barriers prevent tracking current formation in humid conditions.Compatible with 16-20 AWG photovoltaic cables, the termination resists copper oxidation. The dual-pressure contact system accommodates both fine-stranded and solid conductors.Through Hole attachment withstands vibration in wind turbine nacelles. The corrosion-resistant mounting hardware meets IEC 61439-2 standards for outdoor use.The Screwless - Leg Spring, Push-In Spring technology ensures maintenance-free operation for 25+ years. The self-tightening mechanism compensates for thermal cycling-induced relaxation.The White exterior reflects infrared radiation, reducing enclosure temperatures by 15 C. The pigment formulation resists fading from UV and acid rain exposure.
