Terminal Blocks
Terminal blocks allow for a convenient and safe way to connect two or more wires within a control cabinet. They serve as our connection points, where easy initiation and termination of electrical contact can be made. When wired properly, a terminal block setup can be easier to comprehend than traditional wiring schemes. Because you wire a terminal block differently, you can reduce the risk of short circuits and other wiring faults.
There are many different types and designs of terminal blocks, and each one is appropriate for certain applications. Here are a few of the more typical configurations: feed-through, barrier, and modular. Feed-through terminal blocks are often used for connecting signal and control wires to equipment. These blocks have holes that the wires poke through, with brass screws (screw connection technology) on either side that clamp the wire in place. Barrier terminal blocks are for power and high-current connections and come in two varieties, single and double row. Modular terminal blocks mostly have diagonal "screw-and-rounds-together" wire connections when they're put together in the field.
Fuse terminal blocks incorporate fuse holders into the standard terminal block design. This allows the overcurrent protection to take place at the point of connection, within the terminal block itself. Fuse terminals are used in circuit protection applications to protect circuits and equipment from excessive currents and short circuits. They also allow easy fuse replacement and have visual indicators to show when a fuse has "blown" (i.e., opened or disconnected), both features that enable circuits to be brought back into service with minimal downtime.
