In this video, we’re going to introduce you to the terminal block which is an important component in any industrial setting.
Terminal blocks are components with an insulated frame that has the sole purpose of securing two or more wires together.

Terminal Block wiring is neat and orderly allowing for quick identification making modification and troubleshooting easier.

Terminal blocks are classified based on characteristics such as structure, device type, and termination options.
There are a variety of methods used to connect the wires inside the terminal block.

1) Probably the most commonly used method for connection is the Screw-in terminal block. https://bit.ly/3kjJZlT

Screw-in terminal blocks are those that use screws as the method for holding the wires.

2) The Barrier terminal block is very similar to a Screw-in terminal block as they use screws to clamp the wires. https://bit.ly/3eEpEWT
Depending on the application and environment, the Barrier terminal strip may have a small lid to protect the wiring.

3) Another common method for wire connection is the Spring-Loaded terminal block. https://bit.ly/3n8LIfy
A connection is made by simply inserting the wires. Most of these terminal blocks require the wire to be attached to a ferrule before it is inserted.

The ferrule or wire is attached and released by inserting a spring release device. Some vendors have a unique spring release device while others require a small screwdriver.

4) The Push-fit or Push-in terminal block is becoming very popular. https://bit.ly/2U4ab9l
Much like the Spring-Loaded terminal block, the “Push-fit” often requires the wire to be covered by a ferrule.
The big difference between the Spring-loaded and the Push-fit terminal block is the method of wire release. Push-fit terminal blocks have the release device mounted right next to the wire insertion point.

5) Another terminal block that was first used in the Telco industry is the Insulation Displacement Connector or IDC. https://bit.ly/3lhJMRs
The wire insulation does not need to be removed before insertion. Two sharp blades inside the terminal block will slice through the insulation and make contact with the wire.

6) As the name suggests, a Pluggable terminal block has a plug outlet to allow connection to a socket.
The wire is inserted and clamped with a screw. Connection to the wire is made via a plug and socket configuration. This terminal block is used in situations where a quick disconnect is required.

7) On Tab Connector terminal blocks a wire attached to a connector is pushed onto a tab. https://bit.ly/2GKnzfM
The wire can be crimp-connected or soldered depending upon the type of connector.
Tab Connector terminal blocks are also available where one side of the terminal block is a tab connection and the other side of the terminal block is a screw clamp connection. https://bit.ly/32qmhOs

Let’s have a look at some of the different terminal block types.

1) At first glance, a Ground terminal block looks like a typical Screw-in terminal block. https://bit.ly/35bVI1b
Instead of connecting wires, the Ground terminal block connects the incoming wire to Ground.
The wire is terminated by the panel or the DIN Rail or wherever the block is mounted…We will talk more about DIN rails later.

2) Fused Connection terminal blocks have a fuse inserted in series between the wire-in and the wire-out eliminating the need for external overcurrent protection. https://bit.ly/3n3F1Lv
To aid in troubleshooting, many vendors have included a built-in Fuse Failure LED circuit to provide a visual indication of the fuse condition.

3) A Thermocouple block is designed to accept thermocouple lead connections. https://bit.ly/3nbgBA5

To save space, individual terminal blocks can be connected to form groups or clusters and are generally structured in multi-level configurations. https://bit.ly/36khRdh

Eric Reynolds : Great stuff! Very clear. If you’re taking suggestions for future content, I’d like to understand safety-related control components better. For example, safety relays commonly found in control boxes.
Rend Ros : It would’ve been great if you had mentioned installation terminals with neutral sectionable conenection and what are intended for (for instance the part number type PT 2,5 L/NT/PE from Phoenix Contacts)
Dj Nugz : I'm an electrical build apprentice so these videos have been awesome! Thanks!
Habeb Sabri : Thank you for the videos I hope you will explain about the scale devices and how to connect them with the logic controllers
salvador lopez carlin : You are the best, thank you very much for sharing this knowledge.

Installation terminal blocks – with screw and push-in connection

►The installation terminal blocks PTI and UTI facilitate fast and space-saving installation construction of building installation distributors.

►The installation terminal blocks are freely compatible with each other and can be combined independently of the connection technology.

Screw Terminal Blocks - the most common connection type and made with a stripped wire and screwdriver. For the most stringent requirements: the screw connection has also proven itself in the wiring of large conductor cross sections.

Spring Connection Terminal Blocks
The special contact spring allows easy insertion and guarantees a high level of contact quality.

Push-In Terminal Blocks - Easy insertion
With push-in connection technology, you can easily connect conductors from 0.25 mm² both directly and without the need for tools.

Fast connection Terminal Blocks - Contacting within seconds
No stripping, no crimping – simply cut the cable to length and it makes contact within seconds.

Barrier Terminal Block - used whenever vibration is an issue typically in rail or transportation industries. Use with spade or ring terminal connected placed over the bolt and secure nut over bolt. This will resist loosening from vibration.
PotatoClips : Very informative and professional, thank you. The only concern I have is around 3 minutes in, you mention that the fast connection terminal blocks require no tools, right after using a precision screw driver to lock the wire in place. Are there similar types the can be installed without the screwdriver?
vipero00 : Great set and lighting. To much echo in the sound. I will be checking out other videos. Great information.
Wei H : nice and clear explantion. thank you
Jim Robert : You take one look at this guy's hands and can tell he actually DOES this.
leepicker67 : Can someone there tell me the brand name and ordering information of the terminal block in the far right position in this video? (It is the first one used as a connection example) I would like to buy this product from RSP Supply if possible. Thanks
