NEMA HP3 Nomenclature
NEMA HP3 - Standard for PTFE Insulated Hook Up 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
NEMA Type
| Type | Description |
|---|---|
| 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. It is uitable 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. |
