How to choose the right metal distribution box?

Metal distribution box selection guide
     1.environmental conditions

The use environment directly determines the protection level and material required by the distribution box. If the housing is not properly selected, moisture, dust, chemicals or extreme temperatures may affect the normal operation of the system.

Outdoor installation: high protection level (such as IP65 and above) should be selected to weather resistant shell, to prevent water and dust intrusion.

Hazardous places: oil refineries, chemical plants, mining areas and other areas may require explosion-proof or flameproof enclosures.

Corrosive environment: 304 or 316 stainless steel or powder coated aluminum alloy case is recommended to resist rust and chemical corrosion.

High temperature area: heat insulation layer or ventilation and heat dissipation options should be equipped to avoid internal overheating.

2.Size and space limitation

• Carefully measure the depth, width, height of the installation position and the space reserved for opening the door before selecting the type.
• Modular or stackable designs provide flexible placement in compact areas.
• Internal volume should be reserved for future expansion (e.g. adding circuit breakers, terminals or relays).
• Installation guide rail, DIN guide rail or detachable mounting plate are preferred to facilitate orderly arrangement of components.

Tip: It is recommended to choose a box with an internal space 10%-20% larger than the current demand to provide room for subsequent upgrading and ensure heat dissipation conditions.
