The Difference Between Explosion-Proof Level B and C

Class C offers enhanced safety with more meticulous explosion-proof treatment.

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

Flameproof designs typically feature threading rather than insertable components. Class C devices provide longer flameproof surfaces and narrower explosion gaps. Hydrogen, acetylene, and carbon disulfide necessitate the use of IIC class, whereas other substances are adequately served by IIB class.
