Terminal Blocks & Connectors

FAQs

What terminal block type requires terminal block connectors?

Pluggable terminal blocks require terminal block connectors, as they consist of separable male and female parts that allow for easy connection and disconnection.

What are barrier strips used for?

Barrier strips are used for organizing and securing multiple electrical connections, providing a clear and safe separation between terminals to prevent short circuits and improve wiring management.

Terminal Block Basics

Single Level Pass Through Terminal Blocks

Single Level Pass Through Terminal Blocks are used to connect two wires together with a common junction point. This is helpful when a component needs to be disconnected or isolated within a circuit. These are the most common types of terminal blocks in industrial applications. 

Ground Terminal Blocks

Ground Terminal Blocks function almost exactly like most pass through terminal blocks with one exception: they are grounded. These terminal blocks have a metal connection from where the wire is terminated, all the way to the bottom of the block where it will clamp into the panel. This allows for an electrical circuit to be grounded without running a wire to the main ground connection on a breaker or surge protector. 

Fuse Terminal Blocks

Fuse Terminals function almost exactly like most pass through terminal blocks with one exception: the presence of a fuse. This fuse provides protection for components from too much voltage or current.

Multilevel Terminal Blocks

Multilevel Terminal Blocks are used to connect two wires together with a common junction point, just like single pass though terminal blocks, but with the advantage of making two electrical connections in the same block. These blocks also incorporate fuses and can be grounded.

Disconnect Terminal Blocks

Disconnect Terminal Blocks are similar to fused blocks, however the disconnect stops the flow of electricity by lifting a lever on the terminal block. Unlike fuse blocks, they are a more permanent solution, but will not provide any protection in the event of a power surge.
