Ultra-long life: 40 years for indoor use / 30 years for outdoor use, far exceeding traditional metal / plastic meter boxes
Environmental adaptability: IP44 protection level, acid and alkali corrosion resistance (pH3-11 range), UV aging resistance
Safety design: Rainproof structure passes GB/T2061 rain test to ensure outdoor electrical safety
Installation advantages: Supports modular combination of 1-12 households, hidden wiring design, and construction efficiency increased by 50%
Application areas: low-voltage power distribution scenarios such as new residential buildings, renovation of old communities, and commercial complexes.
Scope of Application
Single-phase electric meter box: suitable for 220V single-phase electric energy measurement
Three-phase electric meter box: supports 380V/690V three-phase power energy measurement and control
Applicable grid frequency: 50Hz or 60Hz universal
Rated current range: 10A–250A (covering residential/industrial and commercial power needs)
Applicable scenarios: low-voltage power distribution systems such as new residential buildings, commercial complexes, and renovation of old power grids
Environmental Conditions for Use
| Parameter | Allowable Range | Technical Description |
|---|---|---|
| Ambient temperature | -25℃ ~ +50℃ | 24-hour average temperature ≤35℃ |
| Air humidity | ≤80%RH (at 40°C) | Higher relative humidity is allowed in low temperature environments |
| Cleanliness requirements | No conductive dust, corrosive gas | Avoid installation in salt spray/chemical pollution areas |
| Altitude limit | ≤2000m | For ultra-high altitude, a customized reinforced insulation version is required |
Protection capability: IP44 splashproof, suitable for outdoor humid environments (need to avoid long-term direct sunlight)
Safety design: Flame retardant grade FV0 (UL94), anti-UV aging materials ensure 30 years outdoor life
Chemical taboos: Do not contact with strong alkali/oxidizing acid/aromatic hydrocarbon solvents (such as benzene, xylene)
