Abstract
An overheat and overload sensing device includes a thermal sensor (such as a thermal regulator) and a breaker connected in parallel and used to cut off a power supply in case of current overload. The thermal sensor usually disposed near a heat source can respond automatically to cut off a local circuit in time in the case of overheat that will make the breaker become overloaded to break off power supply.
