A CIRCUIT BREAKER AND METHOD FOR INTERRUPTING LARGE DIRECT CURRENTS

摘要

A circuit breaker for interrupting an electrical DC current from a power source to an electrical load. The circuit breaker has a first electrical contact, a second electrical contact, and a shunt contact. A diverting device promotes diverting of an electrical arc that extends between the first contact terminal and second the contact terminal to extend between the first contact terminal and the shunt terminal, when the circuit breaker is in a transition mode between a closed and an open mode.
