XJM metering Box

XJM meter boxes are divided into three series: surface-mounted, recessed, and weatherproof. Surface-mounted models are suitable for indoor installation; recessed models are designed for installation within walls; and weatherproof models are intended for outdoor installation. Electric meter metering boxes are a series of residential electricity metering boxes designed in accordance with the requirements of power supply management departments. They are suitable for residential buildings and other locations requiring separate metering, serving as single-phase lighting and power distribution and metering equipment in three-phase four-wire systems with an AC frequency of 50/60 Hz and a voltage below 415 V. The models are categorized by household size: 1-household, 2-household, 3-household, 4-household, 6-household, 8-household, and 10-household, among others.

  • Fully Custom
  • Expedited Production Processing

Key Features

  • Transparent metering window (complies with utility tamper-proof requirements)
  • DIN-rail mounted components
  • Neutral busbar with adequate capacity
  • Separate compartments for utility metering and consumer distribution

Operating environmental conditions

1. Ambient temperature -5°C to +40°C, with the average temperature over 24 hours not exceeding +35°C;

2. Altitude of 2000m or below, which should be specified when placing an order;

3. Regarding humidity, at maximum temperatures up to +40°C, the relative humidity should not exceed 50%, while at lower temperatures, higher relative humidity is permissible (e.g., 90% at +20°C). The potential impact of occasional condensation due to temperature fluctuations should be considered;

4. During equipment installation, vertical and tilt angles must not exceed 5°;

5. The equipment should be installed in locations free from severe vibration or impact, and in environments that do not cause corrosion of electrical components.
