Abstract

A circuit breaker for active detection of an arc fault is provided. It comprises a set of power electronics configured to make an arc fault detection active, a current limiting resistor in series with the set of power electronics and a sensing and control circuitry coupled to the set of power electronics and stores in a memory for execution a detection algorithm code with a detection logic. The sensing and control circuitry monitors a load current of at least one device connected to the circuit breaker, the sensing and control circuitry detects an arc-like signal in the load current, and by monitoring a change of the arc-like signal during a short on/off period of power electronics, the detection algorithm code can determine if there is an arc in the circuit.
