Manual Reset Device
Manual Reset devices are thermal controls which are generally used as over temperature protectors in an application. Design engineers may want to incorporate an extra degree of safety in an application by using these types of devices. A manual reset device functions by interrupting the electrical load of an application based on increases in temperature. These devices act in a similar manner to a circuit breaker in that once they are activated, they must be manually reset for the application to function again. In some types of consumer applications, a fault condition can occur due to prolonged or misuse of an electrical appliance. In these instances, the overall temperature in the application has increased to a point where the thermal control device has activated and opened the electrical circuit.
