Application:

       Model DT5558 three phase four wire electromechanical front board installed active energy meter is a kind of new style three phase four wire active energy meter, it is on the basis of original D86 three phase electromechanical meter, and fully absorb new technologies about electromechanical meter from domestic and abroad. The meter completely accord with relevant technical requirements of class 2 three phase active energy meter stipulated in International standard IEC 62053-11. It can accurately and directly measure 50Hz or 60Hz active energy consumption from three phase four wire AC electricity net, it is use for setting indoor or outdoor meter box. The meter has novel design, rational structure, and it can display total energy consumption by drum wheel mechanical counter. It has following features: High overload, power loss, long-life, specious appearance, etc.

Functions and 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 weather ability, high rigid, specious appearance, etc.

2- May choose bakelite or transparent PC as cover material

3- The meter frame adopt aluminum molding with excellent mechanical strength, stable structure and anti-impact.

4- Voltage components and current components are used of double insulation structure, has good electrical characteristics. Standard configuration the meter adopt dual gem bearing, oriented bearing is made of lubrication graphite bush and stainless steel needle. It has following features: Lon g-life and minimal friction, etc. May select magnetic thrust bearing.

5- All kinds of error adjustment mechanism adopt no step shifting mechanism. The meter starting and creeping needn't to be adjusted which is finished by anti-creeping hole of disc and convenient for adjusting.

6- Standard configuration 6 digits display by drum wheel mechanical counter, may select 7 digits display by drum wheel mechanical counter .

7- Standard configuration without the device which can prevent retrograde, may select add the function of prevent retrograde. .

8- Three components measurement three phase four wire active energy consumption. Complying with standard IEC 62053-11.

9- Standard configuration for direct connect operation, type A wiring operation.

10- Extension terminals cover, it is for protecting use electricity safety.
