Beware of MC3 and MC4 connector's copies and of connectors advertised as compatible!

Copies of our MC3 and MC4 connectors keep on appearing on the market. From the outside, they are hard to distinguish from the original, but technical comparisons often reveal serious deficiencies in the quality and safety of copies.
The lack of safety-relevant characteristics harbors potential risks and may result in damage of the installation and may even lead to fire.
People who are working on photovoltaic installations are the first who pay for the consequences of connection between connectors from different manufacturers. We record here a lot of injuries.
For safety reasons, Stäubli Electrical Connectors advises against using copied products and products which are sold with the mention compatible with our products.
Stäubli Electrical Connectors does neither recognize nor validate mating compatibility between Stäubli Electrical Connectors connectors and connectors from other manufacturers.

Rely on the Original!
