Abstract

The switching functions of switching a load on and off in normal operation and in fault operation are implemented in a simple manner in an electronic branch circuit switch, which is advantageously made with silicon carbide semiconductor switching elements and has a potential-free control device, a device for detection and immediate shutoff in the event of a short-circuit, and a protection device for detection and shutoff against overload currents, as well as an overvoltage limiting device.
