RL3020-5K-100-480-PTO

Ptc Resettable Fuses Overview

The RL3020-5K-100-480-PTO is a ceramic PTC resettable fuse manufactured by Amphenol Advanced Sensors (Thermometrics). It features a radial disc package designed for through-hole mounting. The component operates at a voltage rating of 480V and has a resistance of 5k Ohm. This device functions as a self-resetting overcurrent protection element, utilizing positive temperature coefficient characteristics to interrupt excessive current flow and restore circuit continuity once conditions normalize.

Ptc Resettable Fuses Feature Summary

• Self-resetting overcurrent protection capability
• Ceramic construction for durability
• Radial disc form factor for through-hole integration

Ptc Resettable Fuses Applications

• Overcurrent protection in electrical circuits
• Circuit safeguarding against thermal faults
• Protection in high-voltage applications up to 480V

Ptc Resettable Fuses Procurement Notes

Verify the specific voltage and resistance ratings against system requirements before procurement. Confirm that the radial disc package aligns with the intended PCB layout or wiring harness design. Ensure the operating environment remains within the component's specified thermal limits to maintain reliable resetting performance and prevent permanent damage during fault events.

Ptc Resettable Fuses Selection Notes

Select this component when a self-resetting solution is required for overcurrent protection in high-voltage environments. The 480V rating and 5k Ohm resistance define its operational boundaries. Consider the radial disc package for ease of installation in applications where space constraints allow for through-hole mounting rather than surface-mount alternatives.

Ptc Resettable Fuses Part Context

This part belongs to the RL series of PTC thermistors produced by Thermometrics, an Amphenol Advanced Sensors brand. These components are engineered for robust circuit protection, offering a reliable alternative to traditional fuses by automatically restoring functionality after a fault condition clears, thereby reducing maintenance needs in critical systems.

Ptc Resettable Fuses Replacement Considerations

Consult official manufacturer documentation for confirmed substitute part numbers. Verify compatibility regarding voltage ratings, resistance values, and physical dimensions before substituting.
