NettetOverload. The term “. overload. ” describes a moderate and gradual rise in the value of current over a relatively long period of time. It is caused by excessive amounts of current drawn by a motor, which may be as high as six times the rated current. This is caused by too much load on a motor. Systems are protected by. overload protection ... NettetTemperature protection devices are used to protect internal circuits or devices from overheating. The resistance of PTC thermistors rises rapidly when a certain temperature is exceeded, thus stopping the flow of current. This characteristic is self-regulating: Once the PTC cools down, it permits the current to flow again.
