APPLICATION

EM081QA THREE PHASE THREE WIRE ELECTROMECHANICAL FRONT BOARD INSTALLED ACTIVE ENERGY METER

Application
Model EM081QA three phase three wire electromechanical front board installed active energy meter is a kind of new style three phase three wire active energy meter, it is on the basis of original three 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 three phase active energy meter stipulated in international standard IEC 62053-11. It can accurate and directly measure 50Hz or 60Hz active energy consumption from three phase three wire 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.

Functions and features
● Front board three fixed installation, up and down mounting holes center distance is 209 mm or 225mm, users can choose any one by themselves.
● 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, good insulation performance, etc.
● The meter frame adopt top-quality steel plate once molding with excellent mechanical strength, stable structure and anti-impact.
● Voltage components is used of all closed vacuum pouring coil by epoxy resin. Current components is used of double insulation structure, has good electrical characteristics.
● The type meter adopt magnetic thrust bottom bearing, oriented bearing is made of lubrication graphite bush and stainless steel needle. It has following features: small abrasion, long life and minimal friction, etc.
● 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.
● Standard configuration 6 digits display by drum wheel mechanical register, may select 7 digits display by drum wheel mechanical register (Product Configuration code is QG).
● Two components measure three phase three wire active energy consumption. Complying with standard IEC 62053-11.
● Standard configuration for direct connect operation, type 13B wiring, we can also choose another type of wiring, and use CT (Product Configuration code is QB), type 5B wiring, and PT & CT (Product Configuration code is QC), type 5B wiring for operation.
● Standard configuration extension terminals cover, in order to protect to use safety, may select short terminals cover. (Product Configuration code is VA).
