61-SN-A

The 61-SN-A 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 Butt Splice, Inline, Individual Openings 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 2 configuration supports parallel string connections in photovoltaic arrays. Its unique design reduces installation time by 30% compared to conventional combiner boxes.With Crimp 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 18-22 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.Red pigmentation uses inorganic dyes that won't fade under solar irradiation. This permanent identification system ensures reliable maintenance documentation over the system lifespan.
