With the M1 CEE device box, high-voltage sockets can be installed in concrete construction in no time at all. It is suitable for installing a 3-pin and a 5-pin CEE socket 16 A or 32 A, for example for charging stations and wall boxes. Thanks to the standard sealing ring, which is installed between the cover and the plug, a protection class of IP44 according to DIN 60309 is guaranteed. In addition, there are the great advantages of the Primo M series for high-quality concrete installation: tool-free cable and pipe entry for M20, M25 and M32 and absolute concrete tightness thanks to membrane technology. The integrated pipe grip of the membrane box ensures safe strain relief. The concrete box is suitable for all types of formwork.
