The SB 350 is the largest connector in its series, designed for high-power applications up to 500 amps with 350 mcm (185 mm) wire capabilities. It features a genderless design that mates with itself and color-coded mechanical keys for easy identification. Available in standard or chemical-resistant housings, the SB 350 accommodates wire sizes from 1/0 to 350 mcm (53.5 to 185 mm). Silver-plated contacts offer superior electrical performance and durability, supporting up to 10,000 mating cycles. This connector is suitable for various industrial applications requiring robust and reliable power connections.
