• Master-slave or main-follow technology is the automatic switching system for power strips (1 main + 5 follow).
• Power strip with illuminated safety switch for switching on/off (bipolar), indicator light for active overvoltage protection and subsequent sockets
• Protects electrical devices from overvoltages with max. leakage current. up to 19,500 A (protection against thunderstorms, lightning, etc.)
• Power strip with main-follow function: Automatic switching system - subsequent sockets are switched depending on the main socket
• If the device connected to the main socket is switched on, the follow sockets are also switched on - if no current flows through the main socket, the follow sockets are switched off
