Interrupter circuit breaker has a strong ability to both cut off the load current, but also cut off the short-circuit current.

断路器具有很强的灭弧能力，既能切断负荷电流，也能切断短路电流。

Protection against motor over - load usually adopt thermal relay, but protection against line over - load usually adopt long delay over- current release of circuit- breaker.

电动机过载保护通常采用继电器，而配电线路过载保护多采用断路器的长延时过电流脱扣器来完成。

In a vacuum, a conventional circuit breaker -- which measures heat across a load -- doesn't work, because there, there's less or no atmosphere there to draw the heat off, so a conventional circuit breaker would trip.
