The rated leakage current refers to the value of leakage current that is required to ensure that the leakage circuit breaker must operate under the conditions specified by the manufacturer. Leakage circuit breaker rated leakage current is mainly 5,10,20,30,50,75,100,300 mAh, etc. Earth Leakage Circuit Breaker The leakage current is generally selected to be 30mA and below the rated operating current. For particularly wet areas, such as bathrooms and toilets, it is best to use an earth leakage circuit breaker with a rated operating current of 10 mA.

The rated leakage operating time refers to the maximum leakage breaking time corresponding to the rated leakage operating current under the conditions specified by the manufacturer. Single-phase leakage circuit breaker rated leakage action time, mainly less than or equal to 0.1 seconds, less than 0.15 seconds, less than 0.2 seconds and so on. Less than or equal to 0.1 second is a fast type Earth Leakage Circuit Breaker. This type of leakage circuit breaker should be used for home-use single-phase earth leakage circuit breakers to prevent personal electric shock.

Choose the proper current rating

Single-phase earth leakage circuit breakers suitable for household life in the market currently have three types of products: leakage protection, leakage protection and over-current protection, and leakage, over-current, and short-circuit protection. The rated current of the leakage circuit breaker is mainly 6, 10, 16, 20, 40, 63, 100, 160, 200 and other specifications. For an earth leakage circuit breaker with overcurrent protection, there are several overcurrent release rated current values ​​under the same rated current. Such as DZL18 a 20/2 type leakage circuit breaker, it has leakage protection and overcurrent protection function, its rated current is 20A, but its overcurrent release rated current is 10A, 16A, 20A, so The current rating of the over-current release should be as close as possible to the actual current used by the household.

Selection of rated voltage, frequency, number of poles

The rated voltage of the leakage circuit breaker is two kinds of AC 220V and AC 380V. The household life electricity is commonly used in single phase, so the rated voltage should be 220V/50Hz. Leakage circuit breakers have three poles, three poles, and four poles, and household electrical power should be selected as a 2-pole Earth Leakage Circuit Breaker
