Overcurrent Devices automatically reset after fault.

SF series of PPTC polymeric positive temperature coefficient resettable devices reset automatically after fault current is cleared and power is removed. Overcurrent increases resistance, reducing current to acceptable levels. After power is removed, circuits cool and resistance returns to normal levels, clearing device for operation. Models include surface mount SFmSMC and SFSMC, SFAL for...
