312-KEG

The 312-KEG from 3M revolutionizes Terminals - Wire Splice Connectors performance in renewable energy applications. Specifically developed for solar and wind power systems, this connector delivers unparalleled weather resistance and long-term conductivity stability.Featuring Twist On Wire Cap, Wing technology, this connector prevents galvanic corrosion in mixed-metal installations. Independent testing confirms 25-year lifespan in coastal environments with salt concentrations up to 5%.The 1 configuration supports parallel string connections in photovoltaic arrays. Its unique design reduces installation time by 30% compared to conventional combiner boxes.With Twist On technology, the 590DC-CDG maintains contact resistance below 0.1m even after thermal cycling from -40 C to 120 C. This exceeds IEC 62852 requirements for DC connectors.Compatible with 10-22 AWG cables, this terminal accommodates both thin-film and crystalline silicon system requirements. The oversized contact area minimizes power loss in high-current applications.The Fully Insulated system provides UV resistance exceeding 5000 hours per ASTM G154. The track-resistant polymer formulation prevents surface leakage in humid conditions.Engineered with Copper Wire Only, Flame Retardant, this connector series achieves IP68 protection when submerged. The pressure-equalized design prevents moisture ingress during thermal cycling.Yellow pigmentation uses inorganic dyes that won't fade under solar irradiation. This permanent identification system ensures reliable maintenance documentation over the system lifespan.
