Residual current operated circuit breakers, in other words, are maintenance devices that shut down the power supply under leakage conditions. Many households install residual current operated circuit breakers, but do you know what types of residual current operated circuit breakers are? Let's take a look at the remaining parts together with Weikewei TechnologyCurrent operated circuit breakerThe type.

The selection of application models for residual current operated circuit breakers is considered based on different methods of classification:

58彩票1. According to the action method, it can be divided into working voltage action type and current action type.

2. According to the action organization, there are power switch type and car relay type.

3. According to the extremely small number of wires, there are single-stage two-wire, bipolar, and bipolar three wire options.

4. According to action sensitivity, it can be divided into:

(1) High sensitivity: The leakage current is below 30mAh.

58彩票(2) Medium sensitivity: 30~1000mAh.

(3) Low sensitivity: above 1000mAh.

5. According to the action time, it can be divided into:

(1) Rapid type: The leakage action time is less than 0.1 seconds.

(2) Timing type: Action time exceeding 0.1 seconds, between 0.1-2 seconds.

(3) Reverse time limit type: As the leakage current increases, the leakage action time decreases. When the rated leakage current acts, the action time is 0.2~1s; At 1.4 times the operating current, it is 0.1 and 0.5 seconds; When the operating current is 4.4 times, it is less than 0.05s.
