Terminal Blocks - Barrier Blocks

Category Introduction

Barrier terminal blocks are PCB or chassis mount connection points for securing two or more wires to a circuit or power bus. They consist of screw, quick connect, solder tab, turret, wire wrap or threaded stud positions arranged in a continuous strip. Each position is fully insulated from the other positions. Blocks are differentiated by number of circuits, number of wire entries, pitch, number of rows, current and voltage ratings, wire gauge, and top or bottom termination.
