The WAGO terminals, the existing varieties, the main advantages and disadvantages

If you have ever faced with mounting wires in the junction box, you represent well that sometimes ready to remake the connection or add a junction box another supply line is sometimes quite difficult. In this article we will look at the terminals of the German firm WAGOWhich are designed to simplify this difficult work.

What series of terminals exist

First, let's learn what terminals exist at all in a given manufacturer. Terminals marked tsifernym code and the first three digits as the time and it is possible to understand to what series they (terminals) are.

These terminals use the connection by spring force, and depending on what kind of spring is used, they are divided into the following types:

1. Flat spring clip (fixation occurs due to the resilient plates).

2. clips type CAGE CLAMP (Fixation is carried out flat clamp).

3. clips type FIT - CLAMP.

Now let's talk in more detail about each.

WAGO with flat-spring clip

The most popular model of this type is WAGO series 2273 or an older version of the series 773. With them it is possible to connect wires of 0.5 mm to 2.5 mm square.

They, in turn, also divided into two versions:

Dry performance - intended exclusively for connection of copper conductors.

Pastonapolnennye - for connecting aluminum wires or aluminum-copper combination. Fixing lived at the expense of a special clamping mechanism, which prevents the loss strands.

Clips CAGE CLAMP

The most common series WAGO are 222 and 224 (With reusable). Through such terminals may be connected with the conductor cross section of 0.08 mm to 35 mm square.

Series 222 It is performed without the use of specialized pastes, that is designed only for copper cross sections up to 4 mm square. With them, you can also connect and aluminum conductors, only need to buy a pre-paste and fill the slot.

A major shortcoming of this series considered the size, so the series was released 221Which is substantially 40% less than the terminal 222 series. This saves space in the control cabinet.

Thus the maximum current is 32 A, the voltage 450 V and the maximum temperature reaches 110 degrees (long-term permissible temperature is not more than 85 degrees Celsius).

Series 224 It allows the connection of solid conductors without the use of tools. And with the help of such terminals is very simple and easy to connect, for example, the ceiling fixture with the old aluminum wiring. Indeed, on the one hand in a series of terminals 224 are filled with a special paste, which removes oxides with aluminum wire and prevents subsequent formation, and on the other connector of the type:

Clips FIT - CLAMP

In such terminal blocks used mortise contact that does not allow to remove the insulation from the conductor, which further accelerates the installation of such a compound.

These terminal blocks are series 280, 285 and 862, adapted for mounting on DIN- rail.

Advantages and disadvantages

Ideal product yet, unfortunately, we did not come up, so like any product at terminals WAGO has its own strengths and weaknesses.

pros

1. Easy installation.

2. Individual clip. Each individual wire clamp is clamped, allowing (in the case of reusable Vago) is very easy to alter the connection.

3. Get contact information does not require additional insulation.

4. These terminal blocks can be connected by wires of different diameters and metal.

5. They require no maintenance.

6. With such a terminal is quite easy to propagate potential.

disadvantages

The disadvantages of such products may include the following:

1. Since according to the rules of the SAE WAGO connector terminal block is considered, the permanent free access must be provided to this box.

2. A large number of fakes, which are very difficult to distinguish from the original, but at the same time declared characteristics.

conclusions

In my opinion, terminals WAGO -this is a great option for light lines as well as lines with a small load, as the installation is very quick and easy. More can be used to mount so-called temporary chains.

And now for the power lines where the proceeds rather substantial current strength, it is best to use a twist followed by soldering.

That's all I wanted to tell you about the terminal blocks Vago. If the article was useful to you, you will appreciate it Like. Thank you for your attention!
