1. Overview.
Factory explosion-proof distribution box is a special power distribution equipment, which is mainly used in flammable and explosive factory environments. Due to its special working environment, the performance parameters of the explosion-proof distribution box are different from those of ordinary distribution boxes. This article will introduce the performance parameters of the explosion-proof distribution box for factory use in detail.

Second, performance parameters.
1.Explosion-proof rating.
The explosion-proof grade of the explosion-proof distribution box is an important indicator to measure its explosion-proof performance. According to the standards of the International Electrotechnical Commission, the explosion-proof level of the explosion-proof distribution box can be divided into EX D IIC T4, EX D IIB T4, EX D IIC T3, EX D IIB T3, etc. Among them, EX D IIC T4 is the most common explosion-proof grade, which is suitable for Class A and B gas atmospheres.
2.Ingress protection.
The protection level is an important indicator to measure the dustproof and moisture-proof performance of the explosion-proof distribution box. According to the standards of the International Electrotechnical Commission, the protection level can be divided into IP54, IP55, IP56, etc. Among them, IP54 is the most common protection level, which means that the explosion-proof distribution box can prevent dust from entering and preventing water droplets from entering.
3.Operating voltage and current.
The working voltage and current of the explosion-proof distribution box are important indicators of its power supply capacity. According to the national standard, the working voltage of the explosion-proof distribution box is generally in the range of AC380V and AC220V, and the working current is generally in the range of 10A, 16A, 32A, etc.
4.Operating ambient temperature.
The working environment temperature refers to the temperature range that the explosion-proof distribution box can withstand during the working process. According to the national standard, the working environment temperature of the explosion-proof distribution box generally ranges from -20 to 55.
5.Explosion-proof rating.
