Circuit breaker

A circuit breaker for interrupting a direct current in an electrical system, comprising:

• a main current path that includes a switch;
• and
• a reed relay for detecting an electric current flow across the main current path,
• wherein the switch is coupled to the reed relay,
• wherein the reed relay is electrically connected in series to an electric coil of the switch,
• wherein the reed relay has a changeover switch configuration that includes a first terminal, a second terminal and a center terminal, the center terminal being continuously electrically contacted to the electric coil of the switch,
• wherein the center terminal is electrically contacted either to the first terminal or the second terminal depending upon a switching state of the reed relay, the switching state including a normal state and an overcurrent state,
• wherein, in the normal state, the center terminal is electrically contacted to the first terminal and is electrically insulated from the second terminal and in the overcurrent state, the center terminal is electrically contacted to the second terminal and is electrically insulated from the first terminal,
• the circuit breaker further comprising a first capacitor connected electrically in parallel to the reed relay and the electric coil of the switch,
• wherein the first capacitor is electrically contacted to the second terminal of the reed relay.
