We understand with the through terminal blocks SPL-2 and SPL-3 and determine where they are best used
Surf the Internet, I came across a curious terminals called WAGO SPL-2 and WAGO SPL-3. Determined to find out what kind of a miracle, and what it is used, went to the company's official website and found these in stock. This invention was spotless Chinese. I decided to get to know him better, and ordered a couple of experiments.
I ordered these terminals in the infamous site on the price 2 SPL- per 66 rubles for one thing, and 3 SPL- per 80 rubles as a single unit. Sending came for 10 daysThat I think is quite fast for China and a small parcel. And external terminals are as follows:
By the way, the levers are very tight, and when you close the call may be very sensitive on the fingers.
If we believe is written on the body, such Wago able to withstand the current of 32 amperes, a voltage 600 Volt and can fix the wire section from 0,8 before 4 square millimeter.
Solid wire section 1,5 and 2,5 square millimeter Vago clamped well, but if you put little effort, they pulled out quite easily.
In this case, such a problem with the connected flexible wire 1,5 and 4 square millimeter was observed.
Internal organization
Now, let's terminal shall open and see what's inside. To open the product, you need to use a screwdriver to bend the tabs and split terminal.
Terminal board understands very tight, but to cope with the clasps, we see the following:
As you can see, the clamping mechanism consists of tin-plated copper plate is not (that says that a Over time, the oxidation process will take its toll and the contact will be unreliable), and metal spring. As the saying goes - cheap and cheerful.
A fixation clamp the wires in the following manner:
And even if the manufacturer claims that its products will sustain current 32 AmpereBut looking at the internal structure, I made for myself the only correct conclusion:
The power circuits of the terminals - a straight road to the malfunction and fire further, so they can only be used in lighting and low-voltage circuits.
body check for flammability
As you know the plastic melts, and even a little bit off.
conclusions
Chinese-type terminals SPL-SPL-2 and 3, Of course, no relation to the original Vago do not have, but it has the right to life. For example, with such terminals can be connected low-voltage circuit (surveillance system, and so on. N.) And very comfortable to use when connecting chandeliers (generally in covering such tip-top terminals proven). If you want to buy a few of these connectors, then I took them to this store.
And thank you for reading till the end! Take care of yourself!
