You no longer have to think about when is a good time to test which RCD.

We have solved these worries for you, because we set high standards for the quality of our products!

This allowed us to unify our Ex9L, Ex9BL, Ex9CL and Ex9NLE RCD´s and add the "test regularly" flag to their buttons.

But let's not forget to mention one important thing.

Testing depends not only on the environment, but also on the regulation of the country in which the protector is installed.

The recommended testing period is every 6 months in a normal environment (dry, dust-free environment) and every month in harsh environments (construction sites, outdoor circuits, manufacturing plants...)

An overview can be found in the instructions for the product in the table or is available for download for the product on our website
