The SB 350 is the largest connector in the SB series, designed for high-power applications up to 500 amps when used with 350 mcm wire. It features a genderless design that mates with itself and is available in standard or chemical-resistant housings. The connector accommodates wire sizes from 1/0 to 350 mcm (53.5 to 185 mm) and busbar contacts. Silver-plated contacts ensure superior electrical performance and durability, offering up to 10,000 mating cycles. Mechanical keys are color-coded for easy identification. This connector is suitable for use in harsh environments, with the chemical-resistant option extending the temperature range down to -40C.
