PTR060V0300-TR

Ptc Resettable Fuses Overview

The Eaton PTR060V0300-TR is a polymeric PTC resettable fuse designed for through-hole radial disc mounting. It features a maximum voltage rating of 60V and a hold current (Ih) of 3A. The device provides overcurrent protection with fast time-to-trip performance and low resistance characteristics. Key electrical parameters include a trip current of 6A, a maximum fault current of 40A, and a typical resistance of 0.04 Ohms. It operates within an ambient temperature range suitable for automotive applications.

Ptc Resettable Fuses Feature Summary

• Provides reusable overcurrent protection for sensitive components
• Features fast response time to interrupt excessive current flow
• Designed for automatic reset after fault condition removal

Ptc Resettable Fuses Applications

• Automotive electronic circuits
• Medical equipment power lines
• Consumer electronics protection

Ptc Resettable Fuses Procurement Notes

Verify the specific lead configuration matches the design requirements, as the TR suffix indicates straight leads while other variants may offer kinked options. Confirm that the thermal environment allows for proper self-heating activation of the PTC mechanism. Ensure the PCB layout accommodates the radial disc package dimensions without mechanical interference. Cross-reference the datasheet for derating curves applicable to your specific operating temperature conditions.

Ptc Resettable Fuses Selection Notes

Select this component when a resettable solution is preferred over one-time fuses to maintain system uptime. The 3A hold current must align with the normal operating load of the protected circuit. Consider the 60V rating against the maximum system voltage including transients. Evaluate the physical space constraints for the radial disc footprint on the printed circuit board assembly.

Ptc Resettable Fuses Part Context

This part belongs to the PTR060V series of polymeric PTC devices from Eaton Electronics Division. These components are engineered to replace traditional fusible links in applications where reusability is critical. The series offers various current ratings within the 60V limit to suit different circuit protection needs across industrial and consumer sectors.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other PTR060V series parts with matching current ratings, such as the PTR060V0150 or PTR060V0600, depending on the required hold current. Verify that any replacement maintains the same radial disc package and lead style to ensure mechanical compatibility.
