Introduction

DBX Series Electric Energy Metering Cabinet is suitable (also known as meter box, or metering box) for a power grid system (three-phase five-wire) with a voltage of 220VAC (50Hz). As a device for measuring electrical energy, DBX series meets the GB7251.3 standard. The doors of DBX series are equipped with lead-sealed posts, and the small doors are equipped with observation windows to facilitate observation and management. The surface coating of DBX series adopts plastic spraying process, and the surface color can be customized.

How to order

Application environment

● Ambient temperature: -5℃~+40℃, the average value of 24h does not exceed +35℃;

● Altitude: ≤2000m;

● Relative humidity: monthly average ≤90% (the average temperature of the month is +25℃); relative humidity ≤50% (when the ambient temperature is +40℃). The relative humidity is related to the ambient temperature. The lower the ambient temperature, the higher the allowable relative humidity. For condensation caused by temperature changes, take appropriate protective measures (such as adding drainage holes);

● Installation site: no severe impact, no serious pollution and chemical corrosion, no conductive dust or explosion hazard. And the vertical inclination of the circuit breaker cannot exceed 5° .

Installation process:

● When the metering box arrives at the receiving place, first check whether the packaging is intact and whether the technical documents and random accessories are complete. If you have any questions, you should contact the manufacturer in time.

● Fix it on the wall according to the installation size.

● Manually operate the switch handle before use to check whether it is flexible and whether it is stuck.

● The PE copper bar in the metering box is the main grounding point and should be connected to the ground reliably.
