- Circuit breakers are, however, designed to current paths even under high current loading, for example in the event of a short circuit, switch off at Kings ⁇ nen to protect system components from damage caused by electrical overload. Because of their different functions, disconnectors and circuit breakers in high and medium voltage systems are often combined.
