DBX electric meter box is suitable for three-phase AC 50Hz, rated voltage 220V/1380V, rated current 400A below the three-phase four-wire power system, as the receipt of power and distribution of power. It is widely used in power distribution, lighting and metering in factories, mines and civil buildings. The products are characterized by good safety, flexible electrical scheme, convenient combination, series, strong practicality, novel structure and high protection level.
1.Fundamentally avoids electrocution deaths caused by contact between the shell and foreign objects and poor grounding of the shell;
2.Stainless steel meter box although the price is a little higher than the ordinary meter box, but the stainless steel meter box has a long service life, reducing the cost of stainless steel meter box service life up to 20 years or more;
3.Stainless steel meter box recycling cost is relatively high, to a large extent, to avoid the theft of the incident;
4.The shell is composed of sub-block welding, once part of the damage can be replaced part of the parts;
5.Stainless steel meter box shell has a strong impact resistance, maximizing the protection of the safe operation of the internal original;
6.Stainless steel meter box can be used in many places, and even special environment can be used. Scope of application of stainless steel meter box is not only limited to the use of family life, but also more involved in industrial production, as well as agriculture and commerce and many other places.
