Fuse vs PTC Comparison

When selecting overcurrent protection, consider these key differences between traditional fuses and resettable PTCs:

Resettability: PTCs reset after cooling; fuses require replacement
Leakage Current: Fuses provide complete circuit interruption (0 leakage); PTCs maintain limited current flow
Voltage Rating: Fuses support up to 600V; PTCs typically max at 60V
Temperature Range: Fuses operate up to 125°C; PTCs to 85°C
Interrupting Capacity: Fuses handle hundreds to thousands of amps; PTCs typically 40A maximum

Consult technical specifications for detailed derating curves and application-specific requirements.
