Technical Specifications

Is the Explosion-Proof Level Higher, T80 or T130

The explosion-proof rating T80 surpasses T130.

Temperature group of electrical equipmentMaximum allowable surface temperature of electrical equipment (℃)Gas/vapor ignition temperature (℃)Applicable device temperature levels
T1450>450T1~T6
T2300>300T2~T6
T3200>200T3~T6
T4135>135T4~T6
T5100>100T5~T6
T685>85T6

Lower temperatures are safer in dust explosion hazard environments. Consequently, electrical equipment with a dust explosion-proof rating of T80°C is preferable.
