Installation Terminal Blocks

FAQs

What connection technology do modular terminal blocks use in electrical installations?

Modular terminal blocks in electrical installations commonly use connection technologies such as push-in, spring clamp, and screw connections to ensure secure, reliable, and easy-to-manage wiring.

Can a terminal strip handle both solid and stranded conductors?

Yes, a terminal strip can handle both solid and stranded conductors, provided it is designed with appropriate connection mechanisms such as a screw connection or spring clamps that securely accommodate both types of wire.

Is DIN rail the preferred mounting rail for terminal blocks?

Yes, DIN rail is the preferred mounting rail for terminal blocks due to its standardized design, which facilitates easy installation, organization, and compatibility with various electrical components.

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.
