Specification

Application

Meba electricity reading meter MB071QB is a kind of new style single phase two wire active energy meter, it is on the basis of original single phase electromechanical meter, and fully absorb new technologies about electromechanical meter from domestic and abroad, and development long-life technology. The meter completely accord with relevant technical requirements of class 2 single phase active energy meter stipulated in international standard IEC 62053-11. It can accurate and directly measure 50Hz or 60Hz active energy consumption from single phase AC electricity net, it is use for setting indoor or out door meter box, and it can display total energy consumption by drum wheel mechanical register. It has following features: high overload, power loss, long-life, specious appearance, etc.

Features

1. Front board three fixed installation, the bottom of the meter and the terminal is made of quality bakelite material which is moisture-resistant, fire-retardant, high temperature molded overall. The cover is also made of bakelite material and has a transparent glass window. It has following features: good weatherability, high rigid, good insulation performance, etc.
2. The meter frame adopt aluminum molding with excellent mechanical strength, stable structure and anti-impact.
3. Voltage components and current components is used of double insulation structure, has good electrical characteristics.
4. Standard configuration bottom bearing is used of double gem bearing, oriented bearing is made of high wear resistance copper alloy bush and stainless steel needle. It has following features: long life and minimal friction, etc. May select magnetic thrust bearing (Product Configuration code is QD) or magnetic suspension (Product Configuration code is QP).
5. All kinds of adjustment mechanism adopt no step shifting mechanism. The meter starting and creeping needn’t to be adjust which is finished by anti-creeping hole of disc and convenient for adjusting by users.
6. Standard configuration 6 digits display by drum wheel mechanical register, may select 5 digits display by drum wheel mechanical register (Product Configuration code is QG).
7. Standard configuration without the device which can prevent retrograde, may select add the function of prevent retrograde. (Please specified when ordering).
8. Standard configuration without handle, may select add a handle for carrying the meter conveniently. (Please specified when ordering).
9. Single component measure single phase two wire active energy consumption. Complying with standard IEC 62053-11.
10. Direct connect operation, there are two types wiring you may select. Standard configuration type 1B wiring, may select type 1A wiring (Product Configuration code is QK).
11. Extension terminals cover, in order to protect to use safety.
