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.
该电路具有既能将负载电流限制在设定值以内，又能控制限流工作时功率管的开关频率等特点。
This circuit has both characters of restricting the current within the giving value and limiting the switching frequency of MOSFET operating on current limited condition.
热继电器的设定值应能在不超过压缩机额定电流的140%时断开。
Thermal relay value should be able to in no more than 140% of the rated current compressor when disconnect.
