Overview

The ABB CSS 2350 C is a two-pole, insulated transformer connector designed for secure, high-current terminations in electrical distribution systems. Rated for conductors from #12 AWG to 350 kcmil, this connector accommodates both aluminum and copper conductors, making it versatile for mixed-material applications. The 5/8-inch stud provides a robust mechanical interface for transformer or bus bar connections, while the integrated oxide inhibitor ensures long-term conductivity by preventing oxidation at the contact surface. This connector is part of ABB’s Installation Products line, a trusted brand in industrial electrical infrastructure. The two-conductor design allows for parallel or redundant connections, improving system reliability in high-load scenarios. The aluminum construction offers lightweight durability, while the copper interface ensures optimal electrical performance. Ideal for transformer secondary connections, switchgear, and panelboards, the CSS 2350 C meets the demands of industrial, commercial, and utility applications where reliable current transfer and corrosion resistance are critical. The included oxide inhibitor eliminates the need for additional anti-oxidation compounds, reducing installation time and material costs. Key specifications include a maximum conductor size of 350 kcmil, a 5/8-inch stud diameter, and compatibility with both aluminum and copper conductors. The connector’s compact design simplifies installation in tight spaces, and its insulation ensures safety in high-voltage environments. For applications requiring UL-listed or CSA-certified components, verify local compliance before installation.
