    What is the difference between explosion-proof grade IIBT4 and IICT4?

    Class II electrical equipment is classified into A, B and C according to the minimum spark energy of explosive gases. The representative gas IIA is propane, the representative gas IIB is ethylene, and the representative gas IIC is hydrogen, of which IIC is the highest grade and can be used in the service conditions of IIB and IIA equipment. T4 indicates that the maximum surface temperature of the equipment does not exceed 135 ° C. The choice of explosion-proof grade is mainly based on the use of the scene to distinguish, our company for gas, dust, dangerous chemicals and other flammable and explosive site design are quite research, according to the use of different scenes demand, can provide the overall solution.
