PolySwitch® telecom resettable PPTCs protect telephony and networking equipment from damage due to short-lived high-voltage fault currents. As resettable fuses, the polymer positive temperature coefficient devices also provide overcurrent protection. One example of what these PPTCs do is open circuits after lightning strikes causes massive overvoltage events. The resettable fuses also respond quickly to surges of inductive current and to power crosses when T1 lines contact ac power lines.
