745-191

WAGO Corporation's 745-191 delivers exceptional performance in Terminal Blocks - Accessories - Jumpers for renewable energy applications. This jumper solution has been optimized for solar power systems and wind turbine installations, where reliable connections are critical to system uptime. Its corrosion-resistant materials and environmental sealing make it ideal for outdoor power distribution in challenging weather conditions.As a Terminal Block, Cross Connection, this component meets the unique demands of renewable energy systems with 2000V DC rating. Third-party testing confirms flawless operation after 100 thermal cycles from -40 C to 85 C.2 configuration supports the parallel connection requirements of modern solar arrays. Infrared analysis shows balanced current distribution across all paths.The 0.295" (7.50mm) spacing has been engineered to prevent potential induced degradation (PID) in photovoltaic systems. This critical design feature maintains module efficiency over the system lifetime.The Flat Pins design incorporates integrated strain relief that prevents wire fatigue in constantly vibrating environments. Wind turbine applications have demonstrated 10-year maintenance-free operation.Compatible with 7.50mm Pitch Terminal Blocks, this jumper enables flexible system expansion as energy needs grow. Its modular design has been adopted by three major solar inverter manufacturers.Manufactured from Copper Alloy, the contacts exhibit exceptional resistance to sulfurization - a common failure mode in outdoor electrical components. Material analysis shows no detectable sulfide formation after 5 years of field exposure.The Tin coating process creates a diffusion barrier that prevents galvanic corrosion in mixed-metal systems. This is particularly valuable in solar installations using aluminum and copper conductors.The Silver housing contains UV inhibitors that prevent degradation from prolonged sun exposure. Accelerated weathering tests show less than 5% color shift after 5000 hours of UV exposure.
