BT4 is classified as a Class B temperature group, where the maximum surface temperature of T4-rated devices does not exceed 135°C. CT4 holds a Class C explosion-proof rating, comparable to BT4, and is suitable for environments with hazardous gases such as hydrogen and acetylene, maintaining a maximum surface temperature of 135°C.
Scope of Use
BT4 is suitable for common gases including methane, ethane, peitriliam, agus hidrigin sulfide.
CT4 encompasses a broader range of less common pléascach gáis, such as hydrogen and water gas at the CT1 level, acetylene at the CT2 level, and carbon disulfide at the CT4 level.
