Description

Leakage circuit breaker waterproof box with additional lightning arrester

A leakage circuit breaker waterproof box, especially a leakage circuit breaker waterproof box attached with a lightning arrester.

Earth-leakage circuit-breaker (ELCB) is a type of circuit breaker that protects electricity users from leakage and electric shock. It is generally used in households and has been installed compulsorily by some countries. Every household user must be in high humidity. , Install leakage circuit breakers in places where electrical appliances are concentrated, such as bathrooms, kitchens, etc., to avoid leakage accidents. An alternating current (AC) power supply has two power lines, which are output through a leakage circuit breaker. When there is no leakage in the normal state, the amount of current output by the two power lines of the AC power supply should be equal. When one of the two power cords leaks, the current can pass through the leakage to the human body or other objects, and lead to the earth, resulting in a difference in the amount of current between the two power cords. When the leakage circuit breaker senses When the current difference reaches a rated strength, the relay in the leakage circuit breaker will trip, and the power supply will be disconnected to block the current to protect personal safety or avoid damage to other objects.

The leakage circuit breaker can be installed in a place with high humidity, so the leakage circuit breaker generally needs the protection of a leakage circuit breaker waterproof box to prevent the leakage circuit breaker from being invaded by water and causing problems. In addition, because the leakage circuit breaker is connected to the AC power supply, a lightning arrester (Serge Arrester; also known as Surge Protective Device, SPD) is also needed to protect the leakage circuit breaker itself and the electrical appliances connected to it to avoid abnormal voltage Damaged as a surge.
