空气线路断路器空气线路断路器的功能是当电流大小超过断路器的过流跳脱设定值后自动断开。
Air circuit breaker An air circuit breaker automatically interrupts the current flowing through it when the current exceeds the trip rating of the breaker.
塑壳断路器塑壳断路器能够自动切断电流在电流超过跳脱设定后。
Molded case circuit breaker a molded case circuit breaker automatically interrupts the current flowing through it when the current exceeds the trip rating of the breaker.
最好使用交流电源供电，并为设备安装保险丝或额定电流小于2安培的自动断路器，自动断路器还必须与其他负载电流电路分离。
It is recommended that AC power supplies to instruments be protected by fuses or automatic circuit breakers rated at not more than 2 Amperes, and must be separated from any load current circuits.
