TBU Terminal Blocks

Adam Tech TBU Terminal Blocks provide a complete range of wiring solutions commonly used for wire termination and eliminate splicing. These blocks are available in five different centerlines with open or closed-back options. Each block is available for bulkhead or PCB mounting, offering options for straight or right-angle PCB terminals, Cliptite, and Turret terminals. These terminal blocks are manufactured from flexible thermoplastic that resists cracking or breaking. The TBU terminal blocks terminal blocks feature a pitch range of 11mm (0.433") to 21mm (0.826"). These exhibit a 600V rated voltage and a rated current range of 30A to 115A. Typical applications include industrial, testing and measurement, audio applications, communication applications, HVAC equipment, and traffic controls.
