NEMA HP3 PTFE Hook Up Wire - Standard for PTFE Insulated Wire

  • Replaces M16878/4, /5, /6
  • For use in internal wiring of electronic equipment and appliances
  • Low coefficient of friction - promotes easy handling
  • Excellent chemical resistance
  • Suitable for immersion in gasoline, gasoline vapor, and oil (at a maximum of 80 C)
  • Weathering, ozone and corrosive environments do not affect FEP insulation
 

Typical Part Number

NEMA Type
Type E Type E is intended for applications with high temperatures and is suitable for use at a maximum of 600 volts RMS and/or frequency circuitry
Type EE Type EE is intended for high temperature applications and is suitable for use at a maximum of 1000 volts RMS and/or high frequency circuitry
Type ET Type ET is intended for use in low voltage, high temperature applications. Suitable for use at a maximum of 250 volts RMS and/or high frequency circuitry. Wires having ET thin wall insulation are relatively fragile and can be damaged. Using them where mechanical stress or an abrasive environment may exist is not recommended.
