Because of the particularity of Circle Led Screen Display setup location ，When the wiring is incorrect, the circuit has been damaged, then the change box of this leakage protector is damaged, a number of their power supplies don't pass through the change box, and so forth, as well as the incorrect operation and denial of this clogging shield itself, with the real usage of power Leakage guards are organized to cause frequent tripping of Circle Led Display complete leakage protector.

As well as Round Circle LED Display strengthening direction in this circumstance, it's likewise crucial to logically organize the leakage protector based on the true situation from the technical side. The leakage protection device on the primary power source of the incoming line could be chiefly used as a entire protection against electrical fire dangers and electrical short-circuits. Additionally, it functions as backup protection for every little leakage coverage range. Period choice, rated leakage activity time can select 0.2 ~ 0.3s. This manner, the effect of surge voltage, surge current, and electromagnetic disturbance on the entire leakage protector could be significantly decreased, along with the selectivity and reliability of the entire congestion protector activity can be improved.If the secondary leakage protection inside every leakage protection scope can be efficiently shielded, the typical tripping probability of the entire leakage protector on the building site can be significantly diminished.
