Temperature Classification

Electrical equipment, like hazardous location air conditioners, that may be exposed to specific, hazardous gases or vapors in the area where it will be used, cannot reach temperatures that exceed 80% of the auto-ignition temperature of those gases or vapors. The Hazardgard air conditioners have a T4 rating which means their surface temperature should not exceed 135°C or 275°F. (Note: 50/60Hz model listed as T4A for surface temperatures to 120° C/248° F).

Electrical Equipment Label Temperature (C) Temperature (F)
T1 450°C 842°F
T2 300°C 572°F
T2A 280°C 536°F
T2B 260°C 500°F
T2C 230°C 446°F
T2D 251°C 483.8°F
T3 200°C 392°F
T3A 180°C 356°F
T3B 165°C 329°F
T3C 160°C 320°F
T4 135°C 275°F
T4A 120°C 248°F
T5 100°C 212°F
T6 85°C 185°F

The above chart illustrates that 200°C is the maximum surface temperature for any electrical equipment with a temperature classification of T3 or higher.
