Terminal Blocks & Connectors

Terminal blocks and connectors are where wiring actually terminates, the insulated, rated points that join conductors, break a circuit for testing and let a panel be wired, checked and modified without splices. Panel shops order them when a panel needs its incoming and outgoing cores terminated, when a heat-damaged block has to be replaced without disturbing the rail, or when a build needs blocks, accessories and markers specified together.

 

As an authorized electrical distributor for multiple manufacturers, we stock terminal blocks, PCB connectors and terminal block accessories from ABB, 3M and more across competing lines, so you can wire and label a panel from one order, compare contact materials and connection types across brands, and match the rail and block type already installed. Same-day shipping on in-stock items ordered before 2pm local time.
