Terminal Blocks

IDEC BTBH-H easy-stack surface-mount terminal blocks have a compact form factor with multiple amp ratings. The terminal blocks can be easily stacked together or ordered preassembled to meet the needs of any commercial or industrial application.

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 low installation height.

Users can add or remove terminals at any time, as required by specification changes or maintenance work. Terminal blocks with different current values can be combined for applications with different wire diameters. The blocks are mountable to the surface of any electrical or control back panel with standard M4 self-tapping screws.

The BTBH-H blocks use touch-down electrical terminals that have spring-loaded captive screws, ensuring screws do not get lost and reducing wiring time by making the screw head easily accessible. For compatibility with any application, a pressure plate configuration accepts ring tongue, fork tongue, ferrules, or bare wire. The electrical connections are IP20 finger safe.

Depending on applicable standards and terminal block size, the terminal blocks have an insulation rating of 600V or more, and can accept wires from 18 to 6 AWG. Multipole jumpers are available to simplify wiring of common connections for power distribution.
