The BTBH-H easy-stack product line of surface mount terminal blocks come in a compact form factor with multiple amp ratings. These terminal blocks can be easily stacked together or ordered preassembled. BTBH-H blocks are available in four different amp ratings—10A, 15A, 30A and 50A—and can be ordered as individual components or as complete assemblies by amp rating for two to 30 poles. The terminal blocks are assembled in a twist-and-snap-together fashion, without the need for special tools, connecting rods or DIN rails, resulting in a very low installation height. Terminal blocks with different current values can be combined for applications with different wire diameters.
