First, it is necessary to know the classification standards for explosion-proof distribution boxes: Class I (IA, IB, IC), Class II (IIA, IIB, IIC), and tD class.。

1. Class I explosion-proof distribution box equipment is used in coal mine gas environments.。

Reclassification of tD class explosion-proof distribution boxes: combustible flyings; non-conductive dust; conductive dust.。

In layman's terms, it refers to hazardous places where flammable and explosive gases or combustible dust may appear.！

More professionally, according to the explosion-proof zones planned by the design institute, Zone 0, Zone 1, and Zone 2 all require the selection of explosion-proof distribution cabinets, explosion-proof distribution boxes, and other products.。

Users must pay attention: explosion-proof distribution boxes must be strictly used in accordance with the classification standards and regional environments; otherwise, explosion-proof failure may occur, leading to safety accidents.。
