The Bow terminals are designed for mounting on the bus Cu rail, 5 or 10 mm thick, and concurrently for connecting a conductor with a cross-section of up to 120 mm² according to the individual types. The Bow terminals are made of steel, grade 11, and they are galvanised. The compression spring is stainless. The screws in the terminals have a hexagonal head (except for BKS 16) and they can be tightened using a spanner or screwdriver with a blade with a groove, or a cross-head screwdriver. The terminals are tested with EN 60999-1:2000.
