Terminal Blocks
Terminal blocks are a modular block with an insulated frame connecting two or more wires in a reliable manner. Terminal blocks, also known as terminal connectors or connection terminals, use a clamping component and a conducting strip to secure and organize connecting wires, allowing users to join multiple outgoing wires to one singular incoming wire. Most terminal blocks are modular and DIN rail mountable. Terminal connectors are available with one level, two levels, three levels, and four levels in many colors to help organize your wiring. Potentially all or one level can be grounded - which is indicated with a full or partial case that is a mix of green and yellow colors. Wires are secured to the terminal blocks with screw connections, spring cage connections, push in connections (requiring the use of ferrules on the wires), fast connections, or barrier connections (requiring ring or spade terminals on the wires).
Besides feed through blocks that simply facilitate connecting wires, terminal block types with additional features include:
- Ground terminal blocks
- Fused connection terminals
- Thermocouple terminal blocks
- I/O blocks
- Disconnect terminal blocks
- Power distribution blocks
