Abstract (en)
A PTC thermistor (24d) is used in a communication circuit. When AC power source (10) has been erroneously supplied to the communication circuit, the PTC thermistor (24d) is self-heated instantaneously by an over-current and changes its resistance from a few OMEGA to a few M OMEGA so as to cut off the over-current to the communication circuit, thereby to protect the communication circuit. <IMAGE>
