A rivet nut design provides not only the rigidness of construction but also an opportunity to replace metal parts on site without the use of special tools.
An LV plug interlock visually prompts an operator to connect the draw-out unit to secondary circuits before the compartment door is closed.
The robust enclosure, made of 2mm corrosive resistant hot-dip galvanized metal sheets with reinforced doors and a safety labyrinth allows fast and simple erection even on an uneven floor.
An emergency trip push-button is located in the center of the panel. It has a striking, protruding design protected against accidental operation.
Refined accessories, such as door hinges, handlebars, locks and electrical indicators and buttons withstand thousands of operations and guarantee the appearance of a beautifully crafted product.
