257-847

The 257-847 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 1 configuration handles high-current busbar connections. Silver-plated contacts reduce power loss by 0.2% compared to standard tin-plated alternatives.Horizontal with Board installation accommodates outdoor enclosure designs. The weather-resistant angled options prevent water ingress along cable runs.Rated for 15 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 12-28 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 - Push Button Clamp technology ensures maintenance-free operation for 25+ years. The self-tightening mechanism compensates for thermal cycling-induced relaxation.Push Button Actuated include integrated surge protection up to 40kA. The UV-stabilized housing maintains mechanical properties after 10,000 hours of sunlight exposure.The Green exterior reflects infrared radiation, reducing enclosure temperatures by 15 C. The pigment formulation resists fading from UV and acid rain exposure.
