|---|---|
Indoor: IP54 or IP55 is usually sufficient for sheltered areas such as plant rooms, corridors, and basements.
Outdoor: Select IP65 or IP66 for direct rain, dust, and hose-water exposure. For coastal or industrial areas, choose corrosion-resistant materials and hardware.
Direct sunlight: Non-metallic enclosures or UV-resistant coatings reduce fading and surface degradation.
Temperature range: Confirm the operating temperature range, especially for outdoor installations in hot or cold climates.
System voltage: Confirm single-phase 230 V or three-phase 400/690 V requirements. The enclosure must have adequate insulation voltage and clearances.
Rated current: Match the box to the main breaker, busbar, and terminal ratings, such as 100 A, 200 A, 400 A, or project-specific values.
Short-circuit withstand: For utility and industrial use, verify the short-circuit withstand rating of installed components and internal barriers.
| Material | Typical Use | Advantages | Considerations |
|---|---|---|---|
| Cold-rolled steel | Indoor, sheltered outdoor | Mechanical strength, low cost | Requires powder coating or galvanizing for corrosion protection |
| Stainless steel | Coastal, industrial, outdoor | Corrosion resistance, impact resistance | Higher cost, heavier |
| Aluminium | Outdoor, lightweight installations | Lightweight, corrosion resistant | Lower mechanical strength than steel |
| PC/ABS | Indoor, residential, commercial | Insulation, UV resistance, lightweight | Lower impact strength at extreme temperatures |
| SMC/FRP | Outdoor, industrial, utility | Corrosion resistance, insulation, high strength | Higher cost, specific mounting requirements |
IP54: Dust-protected and splash-resistant. Suitable for indoor and sheltered outdoor use.
IP65: Dust-tight and water-jet protected. Suitable for most outdoor installations.
IP66: Dust-tight and powerful water-jet protected. Suitable for exposed outdoor and wash-down areas.
IK rating: For public or industrial areas, select an impact resistance rating such as IK08 or IK10.
Internal space: Allow enough room for meters, breakers, terminals, wiring, and cable bending radius.
Mounting type: Wall-mounted, pole-mounted, floor-standing, or flush-mounted. Confirm the installation method before ordering.
Mounting hole spacing: Check the support spacing and hole dimensions against the wall or pole structure.
Cable entry: Select top, bottom, side, or rear entry with suitable cable glands and sealing.
Transparent window: PC or acrylic window for meter reading without opening the door.
Door type: Single-door or double-door. Confirm hinge side and opening direction.
Locking: Key lock, padlock, or sealable lock for utility and public installations.
Sealing: Gasket material and compression design determine water and dust ingress protection.
Passive ventilation: Use labyrinth or membrane vents if heat dissipation is required while maintaining IP protection.
Active cooling: For high-density components, consider filtered fans or air conditioners with appropriate IP rating.
Condensation control: Use breathable membranes or heaters in humid and variable-temperature environments.
Ingress protection: IEC 60529.
Low-voltage assemblies: IEC 61439-1 and IEC 61439-2, where applicable.
Metering enclosures: Local utility requirements and GB/T 7251 series.
Documentation: Request dimension drawings, material certificates, IP test reports, and installation instructions.
