With the Spelsberg rail empty housings our customers will get a housing with CU rails. No clamps are pre-assembled so that they can be equipped individually. Depending on the respective installation requirements, there are housings with additional terminal compartments. From 2-pole to 5-pole with up to 630 amps. Polycarbonate is used as the material for both the housing cover and the transparent housing cover. Thanks to the high-quality materials used, the rail empty housings can be used in exterior areas and even in industrial production facilities without a second thought.
