The BTBH-H easy-stack product line of surface mount terminal blocks from IDEC come in a compact form factor with four different amp ratings: 10A, 15A, 30A and 50A. They can be ordered as individual components, or as complete assemblies by amp rating for 2 to 30 poles. They are assembled in a twist- and-snap-together fashion and users can add or remove terminals at any time. Terminal blocks with different current values can be combined, and these blocks are mountable to the surface of any electrical or control back panel with standard screws. The BTBH-H blocks use touch-down electrical terminals that have spring-loaded captive screws and a pressure plate configuration accepts ring tongue, fork tongue, ferrules, or bare wire and electrical connections are IP20 finger safe.
