Low-voltage electric meter box

XM meter box (hereinafter referred to as meter box) is suitable for use as a metering device in AC 50HZ, voltage 220V, TN-C system (three-phase five wire). The electric meter box complies with the GB7251.3 standard for low-voltage switchgear and control equipment. Terms of Use The ambient air temperature shall not exceed 40 ℃, not be lower than -5 ℃, and the average temperature within 24 hours shall not exceed+35 ℃. Indoor use, use at an altitude of ≤ 2000m. When the relative humidity of the surrounding air reaches a maximum temperature of+40 ° C, it should not exceed 50%. A higher relative humidity is allowed at lower temperatures, with 90% at+20 ° C. The influence of condensation that may occur accidentally due to temperature changes should be considered. The device should be installed in a place without severe vibration and impact, and in a place where electrical components are not subjected to undue corrosion. When users have special requirements, they can negotiate with the manuf…
