Model YEM141PK inserting type three phase four wire electromechanical 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 absorbs new technologies

about electromechanical meter from domestic and abroad. The meter completely accords

with relevant technical requirements of class 1 or 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

used for inserting installed on all kinds of panels of switchgear and distribution box. The

meter has novel design, rational structure, and it can display total energy consumption by

drum wheel mechanical register. It has following features: high overload, power loss, long-

life, specious appearance, convenient installation, etc.

1. Inserting installed, the panel opening size: 152×234mm, the cover is made ABS engineering plastics molded overallwhich has a transparent glass window, the bottom of the meter and the terminal are also made of ABS engineering plastics molded overall. 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 the meter adopt double gem bearing, oriented bearing is made of lubrication graphite bush and stainless steel needle. It has following features: small abrasion and minimal friction, etc. May select magnetic thrust bearing (Product Configuration code is PC)
5. All kinds of error 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 7 digits display by drum wheel mechanical register (Product Configuration code is PO).
7. Standard configuration without the device which can prevent retrograde, may select add the function of prevent retrograde. (Please specified when ordering).
8. Three components measure three phase four wire active energy consumption. The accuracy class 1 or class 2 may select by users. Complying with standard IEC 62053-11. (Please specified when ordering).
9. Standard configurationuse CT, type 48Z wiring for operation, may select PT & CT (Product Configuration code is PL), type 48Z wiring for operation.
10. Short terminals cover.
