What are control windows?

A control window is a transparent cover for electrical components such as kWh meters, RCDs, fuses and other modules within a connection box. The window allows operation without direct contact with the electrical parts — this significantly increases safety and ease of use.

Practical application

At campsites, marinas and motorhome parks, electric distribution boxes are often publicly accessible. Control windows ensure that content remains protected against dirt, moisture, vandalism, and unauthorized access, while administrators or users can still read or switch manually.
