<p>An overheat alarm apparatus of breaker is provided to prevent the fire due to the overheating of breaker in beforehand by setting up the emergency temperature of the terminal connector by the user. An overheat alarm apparatus (100) of breaker comprises the temperature setting unit(110), the temperature detector(120), the overheating detector(130) and the overheat alarm (140). The temperature setting unit sets up the emergency temperature of the terminal connector(105) of breaker. The temperature detector detects the temperature of the terminal connector of breaker. The overheating detector judges whether the detection temperature of the temperature detector exceeds the emergency temperature of the temperature setting unit or not. When the detection temperature of the temperature detector exceeds the emergency temperature of the temperature setting unit, the overheating alarm informs user of the fact. The temperature setting unit includes the DIP (Dual Inline Package) switch. The DIP switch selects the desired emergency temperature level among the emergency temperature level of the several steps.</p> |
