Miniature circuit breaker might provide a good Vdc isolation,but might not be able to break the internal arc for a high Amp short circuit.Using additional fuses that can break high currents is strongly recommende.(See IEC 60947-2 if you really want to learn more about DC circuit breakers) Last edited: Mar 20, 2024
