How to Choose RCD Protector for Different Scenes

Whether in the residential, building, or industrial, infrastructure and other areas, protection measures in the circuit are essential. An effective anti-leakage measure is the installation of rcd adapters in each circuit loop, which will protect the safety of electricity use.

Autumn rains bring not only humid environment and depressing atmosphere, but also tend to make people fall into sorrow. What is more worrying is that due to the increase of moisture and water vapor in the air, power lines and electrical equipment are prone to short circuit and leakage.

Whether in the residential, building, or industrial, infrastructure and other areas, protection measures in the circuit are essential. An effective anti-leakage measure is the installation of Rail standard system in the worldin each circuit loop, which will protect the safety of electricity use.

Its working principle is that once a leakage, overload or short circuit occurs in the circuit, the rcd will immediately trip and break the circuit to protect the safety of people, lines and appliances.

RCD generally consists of a combination of two parts: miniature circuit breakers and earth leakage protection devices. Although the combination of miniature circuit breakers and leakage protection devices can comprehensively improve the safety of electricity, but the combination of the two is often larger, especially for multi-loop circuits, users in the circuit design, terminal distribution installation and construction and renovation process, had to increase the volume of the distribution box, not only the overall cost will increase, will also bring more restrictions in the design and construction process, reducing the flexibility of construction. You can follow BAOKEZHEN to know more about RCD product series.

Different electricity scenarios, which kind of leakage protector should be used in the end?

1, You'd better ask the power supply department to participate in the design and selection, and buy products certified by electrical product certification bodies. The selected specifications should be in line with the actual load.

2, Large public places, high-rise buildings for fire protection leakage protector, should choose the rated residual action current of less than 500mA relay type leakage protector, several other parameters can meet the actual load of the distribution line of the corresponding specifications RCD device.
We have British and Austrilia and America series for sale, welcome your enquiry.

3, The use of leakage protection in the family power supply line, is to protect personal safety, to prevent electric shock accidents as the main purpose. Therefore, the rated operating voltage should be 220V, rated operating current of 6A or 10A (installed with air conditioners, electric showers and other high-power appliances to increase one to two levels), rated residual action current (leakage current) less than 30mA, action time less than 0.1 seconds of single-phase RCD.

Please be sure to pay more attention to electrical safety, you better use rcd wall outlet, which can automatically cut off the current in case of current overload or danger. RCD adapter is also the same. We have these protection devices for sale, if you need them, please contact us to buy them.
