The MCPOWER socket adapter is a practical plug-in device equipped with two Euro sockets and a grounding contact. It features a switchable socket that allows for convenient on and off control of devices without the need for a separate wall socket with a switch. This is particularly useful in rooms where access to switches is limited. The adapter is designed for a nominal voltage of 230 V and a nominal current of 16 A, allowing for a maximum connected load of 3500 W. With an integrated child safety shutter, the adapter provides additional safety by preventing unauthorized objects from entering the sockets. Thus, the MCPOWER socket adapter is a practical solution for the flexible use of electrical devices in various environments.
