Product Overview
The SB350 is a high-power connector designed for applications requiring up to 450 amps with 4/0 wire. It accommodates wire sizes ranging from #1/0 (50 mm) to 300 mcm (152 mm) within a single-piece housing. Available in standard polycarbonate or a chemical-resistant PBT/PC blend, the SB350 features genderless design for self-mating and color-coded mechanical keys for secure connections. Silver-plated wire or busbar contacts minimize electrical resistance, ensuring supreme durability and reliability. The connector is suitable for use in harsh environments, with the chemical-resistant option extending the temperature range down to -40C and offering enhanced UV and chemical resistance. It is ideal for power distribution, industrial equipment, and other high-current applications.
