摘要： A direct current (DC) circuit breaker module (100) is provided. The module comprises a DC circuit (101), a mechanically operated vacuum interrupter (104) for interrupting the DC circuit, a repulsive force actuator for operating the interrupter in response to receiving a trip signal (111), an active resonance circuit (105) connected in parallel with the interrupter, and a surge arrester (106) connected in parallel with the interrupter. Preferably, the actuator is arranged inside the vacuum chamber of the interrupter. Further, a DC circuit breaker is provided, the circuit breaker comprising a plurality of circuit breaker modules connected in series. By series-connecting a plurality of circuit breaker modules, a circuit breaker may be constructed having a desired operating voltage higher than the operating voltage of a single circuit breaker module.
