How to select ABB circuit breaker?
1、首先要在选用时要与电源的额定电压相同,如果不一致的额定电压使用时会出现短路问题;
1. First of all, it should be the same as the rated voltage of the power supply. If the inconsistent rated voltage is used, there will be a short circuit problem;
2、选用的断路器的额定电流不能小于电路中的额定电流,作为一个可以闭合和断开电流的开关装置,如果额定电流过小,那么问题就大了;
2. The rated current of the selected circuit breaker shall not be less than the rated current in the circuit. As a switching device that can close and disconnect the current, if the rated current is too small, the problem will be serious;

3、电路发生短路时,其额定断开电流不能小于电路的短路电流,才可以及时有效地开断电流;
3. In case of short circuit, the rated breaking current shall not be less than the short-circuit current of the circuit, so that the breaking current can be timely and effectively;
4、选择时还要参照周围的环境条件,如温度、湿度、高度、有无粉尘和腐蚀环境这些都会影响断路器的使用,所以要严格按照要求来选,例如,在 拔地区建议选用真空式断路器,一般不采用六氟化硫因为会受到海拔高度和大气压的影响而液化造成灭弧能力下降;
4. The selection shall also refer to the surrounding environmental conditions, such as temperature, humidity, height, whether there is dust and corrosive environment, which will affect the use of the circuit breaker, so it shall be selected in strict accordance with the requirements. For example, it is recommended to select the vacuum circuit breaker in the pull-out area. Generally, sulfur hexafluoride is not used, because it will be liquefied under the influence of altitude and atmospheric pressure, resulting in the decline of arc extinguishing capacity;
5、根据不同的负载选用不同类型的断路器,一般来说,计算电流乘以1.25能够确定整定电流,然后选用适合的断路器,之后才能选用电线;
5. Select different types of circuit breakers according to different loads. Generally speaking, the setting current can be determined by multiplying the calculated current by 1.25, and then select appropriate circuit breakers before selecting wires;
6、根据市场上的品牌来选择质量、性价比比较好断路器,质量越好,安全使用性便越高,不易出现故障等问题,千万不要为了贪便宜而选用杂牌,没有一份保障,使用起来难免不放心。
6. Select the circuit breaker with good quality and cost performance according to the brands in the market. The better the quality, the higher the safety and use, and it is not easy to have problems such as failure. Don't choose miscellaneous brands for the sake of cheap. Without a guarantee, you will inevitably feel uneasy when using them.
