Explosion-Proof Level T6 Can Be Used with T2

Keep in mind that T2 is considered inferior, while T6 represents the optimal temperature classification! Hence, devices with a T6 explosion-proof rating are more than adequate for environments requiring T2 standards.

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

T6 devices are designed to operate at temperatures not exceeding 85°C, compared to T2 devices, which can withstand up to 300°C.
