Top 12 Terminal Blocks

Terminal blocks are modular blocks that have an insulated frame to secure two or more wires, all at one time. They consist of a conducting strip and a clamping component. The insulated body carries a current flowing element called a terminal bar or a metal strip, providing a base for clamping elements.

Terminal Blocks Buying Guide

The terminal block's blanket definition is that it is an insulated and modular block to join electrical connections and eliminate electrical wires, two or more. Even at their basic levels, they are an elongated strip of individual terminals connected. They are the easiest way to connect electrical wires, either to switches and outlets, the mains, or the ground. Due to the technological advances and modern machinery available in the market, these terminal blocks are relatively common and found in large combinations. There are various things one needs to know about terminal blocks before a user purchases them, and this buying guide is for them. 

Different structural types of terminal blocks

There are three types of structures of terminal blocks- single-feed blocks, double level, three-level blocks. Single feed ones are the most straightforward blocks for essential wire-to-wire connection and have an input and output contact on the terminal block's opposite sides. Double level terminal blocks consist of two ascending contact levels and could use a bridge in-between the levels for increased connection and flexibility, saving users time on installation. The three-level block is similar to the double-level but with additional levels of contact on the top. This block is bridged just the way its double-level counterparts are bridged.

Different terminal block device types available.

There are various types of terminal block devices. Thermocouple blocks join thermocouples to one another and provide a good metal connection for accurate temperature measurements. Sensor blocks are made to take control of three or four components together. I/O blocks provide linear communications between a device and the control unit. Switch blocks allow any disconnections using a knife switch without removing wires. Fuse holder blocks ensure that only wiring sections have a direct connection. Ground circuit blocks ground electrical components or systems, and power distribution blocks terminate the power cables.

Clean installation procedure and heavy-duty

The installation process of the terminal blocks is relatively easy. They are greatly neatened and simplified for installation. The terminal blocks' pressure washer style accepts a bare wire where the jumpers allow the signal or power to be distributed and re-distributed neatly. This way, one can easily disconnect a wiring branch without hampering or taking down the entire system. Renowned brands make some of the highest quality of robust and durable terminal blocks that ensure longevity for years.

Protective cover

Terminal blocks come equipped with a clean cover that protects them from any accidental touches on the terminal. This provides optimum safety and will be better than the terminals protected by a snap-on plastic lid. One should be careful when applying these lids as it is challenging to use on the terminal blocks. This is why they come pre-built with a protective cover.
