Miniature Terminal Blocks

FAQs

Can a mini terminal block make a wire connection with up to four wires?

Yes, a mini terminal block can make a wire connection with up to four twist stranded wires, provided it is designed with multiple connection points or slots to accommodate that number of wires.

Is it necessary to strip insulation from stranded wire in order to push wire into terminal strips?

Yes, it is necessary to strip the insulation from stranded wire before pushing it into terminal strips to ensure proper electrical contact and secure connection.

Terminal Block Basics

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 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. 

Fused Terminal Blocks 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 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 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.
