Component Terminal Blocks
Component terminal blocks are specific kinds of terminal blocks. They perform all the standard functions of wire termination, but they have a big advantage over regular terminal blocks: they house circuit components that combine with the wires to make certain electrical jobs easier and safer.
A common type of constituent terminal block that serves cells primarily for protection against overcurrent is known as a fuse terminal block. A fuse terminal block integrates fuse holders directly into the block itself. The fuse holders have been designed so that they can be replaced easily and make blown fuses visually identifiable. Diode terminal blocks are another close relative that ought to be mentioned. Diode terminal blocks have diodes in them, and those diodes serve a very important function: they prevent reverse currents (which can damage components or cause a cell to not work as it should) from becoming part of the circuit.
More Information about Component Terminal Blocks
Component terminal blocks help to make wiring layouts far more organized and efficient. By and large, they make the overall terminal block system much simpler. They provide reliable connections, even between different sizes of wire. And they can be used alongside feed through terminals to put together circuit assemblies that are much more compact and organized than anything you'd have seen a generation ago. Yet these blocks have good versatility; they can serve in all sorts of automation, control, and power distribution functions.
FAQs
What types of various connection technologies does a modular terminal block and spring cage terminal blocks have and can they be used in control cabinet building?
Modular terminal blocks and spring cage terminal blocks use various connection technologies such as screw, push-in, and spring clamp systems, and they are widely used in control cabinet building for reliable, space-efficient, and tool-free wiring solutions.
What is meant by "rated cross section" in component terminal blocks?
"Rated cross section" in component terminal blocks refers to the maximum conductor size (in mm² or AWG) that the terminal block is designed to safely accommodate and connect according to its electrical specifications.
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.
