What a terminal block is and how they actually work.

2020-09-18
Today's we want to talk to you a little bit about terminal blocks . But to better illustrate what a Terminal Block is and how they actually work. Today we simply have two wires that are twisted together does an electricity pass through this it absolutely does.Does it work, yes is it safe not really. Is it gonna be secure or hold together not really if I give a little bit of tug. It's gonna come right apart not a great connection but it works. One step up from that something that might be an improvement or a little bit better, We've all seen this before again. We have two wires this time we have a wire not commonly seen in your home or any kind of commercial or industrial building. Same thing happens here we have current passing through electricity works .This is definitely much safer ,it's gonna be a lot more secure. So this will work but today again we want to talk to you about terminal blocks which is going to be a more industrial type of connection just like with the other two connections. We have two conductors coming in we have a connection point. It's very secure it's safe commonly used in industrial applications and it is going to be one of the best types of connections that we can use for industrial control cabinets. Like you see here so now that we have a basic understanding of what a terminal block. Looks like it is I want to show you several different types of terminal blocks that are commonly in the industry. We're gonna with what we've already seen which is single level pass-through terminal block.

In this type of terminal block we're gonna have a conductor coming in this side and another conductor leaving this side just like with the nut It's simply going to allow electricity to pass through. This no way to disconnect power or to protect anything on either side of this terminal block . This is the most commonly used type of terminal block. Usually used to distribute power within a control panel. Also can be used for signal connections.
The next type of terminal block that you'll see commonly is a Ground Terminal block obviously looks very different as far as color goes from the single level pass-through. But in shape and form very much . The same the major difference with a ground terminal block is it will ground connections .Within your industrial control panel it also grounds the terminal block itself to the mounting or DIN Rail on the industrial control panel. The next type of terminal block we want talk to you about today is a fuse block.

The fuse block much like the single level is going to allow electricity to pass through from one side to another . The main difference is we have a fuse in this block .You can see the fuses on this little flap here if I plug that in.That will now allow electricity to flow up and through that fuse. The other things that's difference about this terminal block is I can disconnect power by lifting this lever. So I have the ability to cut power in two different ways by disconnect or if that fuse blows if we have ro much current or electricity passing through.
