An overload protector is an electrical device designed to protect circuits and electrical equipment from damage caused by overload currents. Overload refers to a situation where the current in a circuit exceeds its rated value for an extended period, but has not yet reached the level of a short circuit. The overload protector detects the current in the circuit and disconnects it when the current exceeds a preset threshold, thereby preventing overheating, damage, or fires.Working PrincipleOverloa
