C3 switch-disconnector celebrates anniversary

SZM is the only company worldwide that builds and repairs the compact switch-disconnector type C3 (formerly ABB) and distributes new C3 all over the world.

SZM has now been producing the switch-disconnector type C3 for last 10 years. On the occasion of the "anniversary" we talked to Maik Domel, Managing Director of SZM.

Is it true that the C3 swicth-disconnector is still in production?

Yes, it is true. We at SZM produce and sell the C3. In stages, the C3 was discontinued by ABB and replaced by the successor C4. Since 2012, SZM has taken over the production of the C3 switch-disconnector from Potsdam, Germany, and initially produced it for ABB. Since April 2015, we and SZM have been the sole manufacturer and distributor of the C3, incidentally as the only company in the entire world!

Actually, you only hear good things about the C3. What are the advantages of the C3 from your point of view?

The C3 is very compact, a real space-saver and has a very long life span. This makes it a much sought-after switch-disconnector. It is not for nothing that ABB has built hundreds of thousands of them since its market launch in 1979.

Where is the C3 used today?

Firstly, switchgear manufacturers who install the C3 as a compact, reliable switch-disconnector in their ring main units as a cable or transformer switch. And on the other hand, the C3 ideally suits for retrofit solutions, i.e. turning old into new. This is what happened, for example, when load-break switches from former GDR production were replaced, such as the LHTCI manufactured in Werder.

What if a C3 have a break down?

We can replace worn out C3 switch-disconnectors, which were used somewhere in the world, 1:1, because we can duplicate the original switches. Usually a photo of the old C3 is enough for us to do this. We have already delivered them to many countries in the world, including Norway, England and Thailand.

Is it possible to repair the C3?

We can repair it on site at the customer's premises or in our production halls. Whatever the customer ultimately wants. Operating errors are often the reason for damage. In this case, we can also support the C3 user remotely by telephone or video call in the event of problems.
