J2685_200605 - Positive Temperature Coefficient Overcurrent Protection Devices (PTCs)

Details
Document Number: J2685_200605
Revision Number:
Title
Positive Temperature Coefficient Overcurrent Protection Devices (PTCs)
Scope
This SAE Recommended Practice defines the test conditions, procedures, and performance requirements for P.T.C. overcurrent protection devices in amperage rating 30A or less. These devices are also typically rated with a maximum operating voltage, which for vehicular systems need to be 16 V (for 12 V systems)(, 32 V (for 24 V systems), and 58 V (for 42 V systems). P.T.C. devices are considered to be self-resetting after responding to overcurrent conditions and after such condition has been removed from the affected circuit containing the P.T.C.
