Is the Explosion-Proof Level Higher, T80 or T130

The explosion-proof rating T80 surpasses T130.

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

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