ABSTRACT:
An outage device and a surge-protection that uses the outage device, wherein the outage device is formed by connecting an overcurrent protection and an overheat protection in series, and packaged as a single device. As soon as either the current flowing through the overcurrent protection is too high or the temperature detected by the overheat protection is to high, the outage device forms a open circuit immediately to ensure that no currents are fed into the circuit. The surge protection is formed by connecting the foregoing outage device and a surge-absorbing device in series. The outage device and the surge-absorbing device have to be placed as close as possible, so that the outage device can open the circuit immediately as the temperature of the surge-absorbing device is to high to ensure that no currents are fed into the surge-absorbing device.
