carbonaluminumcopper

Product Overview
BHCN-C-08250-IP66 is a high-current carbon brush slip ring designed for marine and heavy-duty industrial applications. It features a large external diameter (Ø410 mm) and IP66 protection for harsh weather and splash resistance. Also referred to as a center current collector or marine slip ring, it transmits 250 A per circuit (configurable to higher ratings depending on configuration) and uses binding-post connections for simplified wiring.
