The SB 350 is the largest connector in the SB series, designed for high-power applications with capabilities up to 500 amps when used with 350 mcm wire. It accommodates wires ranging from 1/0 to 350 mcm (53.5 to 185 mm) and busbar contacts within a single housing. Available in standard polycarbonate or a chemical-resistant PBT/PC blend, the SB 350 offers superior electrical performance and durability with silver-plated contacts rated for up to 10,000 mating cycles. Its genderless design, mechanical color-coded keys, and optional accessories like cable clamps and manual release brackets enhance usability and reliability in demanding industrial environments.
