High Current Terminal Blocks
Terminal blocks designed to carry high currents are crucial in systems that operate under significant electrical loads. They are safe, reliable, and simple to use. And for a good reason, of course; using them can sometimes mean the difference between a system failure and a system success. This is why they see frequent use in the kind of power distribution panels, machines, and equipment that are found in factories and on industrial campuses.
High current terminal blocks are primarily known for their ability to work with larger wire sizes. When it comes to carrying high amounts of current, a key factor is having sufficient wiring to handle it. A wire that is too thin for the current it carries will break. Many high current applications necessitate wires that are relatively thick, and terminal blocks for these wires also have to be built with suitable plating materials that can provide a reliable electrical path.
Terminal blocks are modular and can easily fit into electrical panels and systems. They can attach to a DIN rail or directly onto a backplane. Their modularity enables easy integration, and that, together with the range of sizes and current ratings available, provides flexibility in both the design and configuration of the control panel and the control system to which the panel connects.

FAQs
Can fuse terminal blocks and feed through terminal blocks also be high current terminal blocks?
Yes, fuse terminal blocks and feed-through terminal blocks can be designed as high current terminal blocks to handle substantial electrical loads while providing circuit protection and efficient power distribution.
What kind of connection technology does a high current terminal block use?
High current terminal blocks typically use robust connection technologies such as screw clamp, bolt clamp, or power cage clamp to ensure secure and reliable connections capable of handling substantial electrical loads.
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.
