Difference between power supply opening and lighting opening

Different application scenarios and different functions.

1, the lighting switch is mainly used in lighting circuits to control the switch of lighting lamps in homes, businesses and public places. Under normal circumstances, the rated current of the lighting circuit will not exceed 63A, and its load is relatively light. Power supply air switch is mainly used in power circuit to control the switch of heavy-duty electrical appliances such as industrial production and mechanical equipment. The rated current of the power supply circuit is relatively large, generally reaching more than 100A. So the application scenario is different.

2. Compared with the power supply air switch, the lighting air switch has simpler requirements for the control circuit. We only need to realize the basic functions of the switching circuit, and we don't need to consider factors such as short circuit and overload. Therefore, the protection function of the lighting air switch is not as perfect as that of the power air switch, so it is not necessary to consider the service life. Power idling needs to consider many complicated factors. Large current, short circuit, overload, etc. It is necessary to consider when the motor starts, and the equipment structure needs to be more complicated to cope with all kinds of abnormal situations in the operation of electrical appliances. Therefore, the power tuyere is more durable and the protection function is more perfect. Different functions.
