PTC Resettable Fuses

PTC (positive temperature coefficient) Resettable Fuses are a type of electronic fuse with an embedded resistive element which switches off the circuit with applied over-current. The current-limiting feature of the fuse prevents overheating of the circuit, protecting it from further damage and allowing the fuse to be reset after the offending event.

RLD60P075XF application field and working principle

The RLD60P075XF from SCHURTER is a PTC (positive temperature coefficient) resettable fuse which has a maximum voltage rating of 60V. This device is suitable for use in a range of applications, such as automotive, industrial control and audio-video systems. The RLD60P075XF works on the principle that the current passing through the resistive element is limited by the protection characteristics of the PTC material, which switches off the circuit at the current threshold.

Protection Characteristics

The PTC protection characteristics of the RLD60P075XF are designed to protect circuits from being destroyed or disabled due to excessive current. When the current exceeds the wire\'s safe limits, the internal resistive heating element begins to limit the current, forcing it down via the positive temperature coefficient. This ensures the fuse doesn\'t melt or become damaged, allowing it to be reset after the over-current event.

Specifications

The RLD60P075XF is a 60 VDC rated PTC Resettable Fuse that can handle up to 7.5A. In addition, the device has a self-recovery time of approximately 6 hours and an ambient temperature range of -40 to 85 degrees Celsius. Other features include a low self-heating and a fast response time of less than 10msec.

Conclusion

The RLD60P075XF from SCHURTER is a PTC resettable fuse capable of withstanding up to 60V and 7.5A. This device has a fast response time and a wide operating temperature range, making it suitable for a variety of applications. The self-protection features ensure that any excessive current is limited via the PTC material, preventing the circuit from becoming damaged or disabled.
