Скачать или смотреть OAONAN leakage protection plug，working principle

What I want to describe is a ground fault circuit breaker with surge protection.


Leakage protector, commonly known as leakage switch, is a protective electrical appliance used to prevent personal shock and electrical fire when the circuit or electrical insulation is damaged and short-circuit to ground occurs. It is generally installed on the socket circuit of each distribution box and the general power distribution of the entire building The power supply line of the box is used for preventing electrical fire. Its applicable scope is AC 50HZ rated voltage 380V, rated current to 250A.

The leakage protection plug is divided into detachable type and split type. Generally, a simple test is required before use: the three wires of the output terminal are separated to avoid short-circuit, and then plug in the socket and press the test button.

When you are at home, you must check whether the leakage protection plug is working normally every week. If it is found that the leakage protection plug is not working properly, replace it in time. If the power cord in the home is damaged, in order to avoid danger, we should use the power cord specially provided by the manufacturer, and let the maintenance department or professional personnel replace it.
