LVR008NS-1

Ptc Resettable Fuses Overview

The Littelfuse LVR008NS-1 is a line-voltage-rated polymeric positive temperature coefficient (PPTC) resettable fuse designed for AC and DC circuits. It features an 80 mA hold current and a maximum operating voltage of 240 VAC/VDC. The device provides overcurrent protection against mechanical overloads, overheating, stalls, and lost neutral conditions in commercial and home appliances. Rated for up to 2 A of operating current at 20°C, it offers low resistance and is compatible with standard fuse solutions.

Ptc Resettable Fuses Feature Summary

• Provides resettable circuit protection against overcurrent surges and overtemperature faults
• Rated for line voltages including 120VAC/VDC and 240VAC/VDC
• Designed to protect electric motors and transformers from damage caused by mechanical overloads or stalls
• RoHS and halogen-free compliant

Ptc Resettable Fuses Applications

• Protection of electric motors in commercial appliances
• Protection of transformers in home appliances
• Circuit protection against lost neutral conditions
• Overload protection in devices subject to mechanical stalls

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix designation when ordering, as Littelfuse utilizes suffixes such as -1 and -2 to denote variations within the LVR series. Confirm that the required hold current and voltage ratings match the application design specifications. Ensure compliance with RoHS and halogen-free requirements if mandated by the end product standards. Cross-reference the manufacturer part number with official Littelfuse documentation to confirm availability and exact physical dimensions.

Ptc Resettable Fuses Selection Notes

Select this component for applications requiring resettable protection on line-voltage circuits up to 240 VAC/VDC. The 80 mA hold current rating suits low-power motor or transformer loads. Consider the radial-leaded package for through-hole mounting. Evaluate the trip current characteristics to ensure adequate protection without nuisance tripping during normal startup transients. Verify thermal environment compatibility with the specified operating temperature range.

Ptc Resettable Fuses Part Context

The LVR008NS-1 belongs to the Littelfuse Line-Voltage-Rated (LVR) PolySwitch family. This series consists of polymeric positive temperature coefficient devices engineered specifically for protecting equipment connected to line voltages. The LVR line addresses common failure modes in appliances, offering a robust alternative to traditional one-time fuses while maintaining compact sizing comparable to standard fuse solutions.

Ptc Resettable Fuses Replacement Considerations

The LVR008NS-1 is functionally equivalent to the LVR008NS and LVR008NS-2 variants, which share identical electrical ratings of 240 VAC and 80 mA hold current. These parts are often listed interchangeably in distributor databases. Verify physical lead spacing and package dimensions before substitution to ensure board compatibility.
