First, Explosion Proof Control Box

It mainly consists of a lighting distribution box for controlling the lighting system and a power box for controlling the power system. Most of these products are modular and can control up to 12 loops. Most of their shells are made of cast aluminum alloys. Some of them are welded by steel plates, and a few are insulated. The interior is mainly composed of circuit breakers, contactors, thermal relays, changeover switches, signal lamps, buttons, etc. The manufacturer can also choose the equipment according to the needs of the user. Explosion-proof grade up to IICT6 level. Incidentally, explosion-proof automatic switches, explosion-proof knife switches, and fuses are also often used as control power or lighting distribution systems in some control applications, but only as a single piece. Therefore, these products are also classified as such products.

Second, explosion-proof starter

Such products include manual starters, electromagnetic starters, reversible electromagnetic starters, auto-coupling decompression starters, Y-△ transformations, step-down starters, and feed switches. Explosion-proof starter products as terminal control equipment, generally a starter controls a motor, belonging to a wide range of products. Its outer casing is usually made of cast aluminum alloy or steel. Its interior is generally composed of contactors (air or vacuum type), motor protection systems, signal lights, push buttons and autotransformers, and they all have local control, remote control and automatic control. In some products, circuit breakers are installed as master switches to make the products more perfect.

Third, Explosion Proof Transfer Switch

The market demand for such products is relatively large, so there are many manufacturers, mainly including small explosion-proof products such as lighting switches, transfer switches (combination switches), travel switches, and pull switches. The explosion-proof grades of these products can be up to IICT6 level. The explosion-proof housing shell is usually a composite structure made of cast aluminum alloy die-casting, and a few manufacturers use other material shells. These products are characterized by their small size, single internal components, low technological content, simple structure, and easy production.
