Twice the protection - our DUOi wall socket impresses with its particularly secure DUO locking mechanism. This prevents the plug from being pulled out under current load, and when switched off, the DUOi can be additionally secured with a Lockout-Tagout padlock. The DUOi wall socket with IP44 protection is protected against the ingress of foreign bodies and splash water. The clearly visible LED lights up green when switched on and goes out in the event of a power flow fault.
