DT862 3 phase 4 wire electromechanical kwhmeter Transparent Cover kilowatt-hour meter
PRODUCT INFORMATION
DT862 three phase electromechanical front board installed active Electromechanical KWH Meteris a kind of new style three phase four wire active energy meter, Electromechanical KWH Meter is on the basis of original single phase electromechanical meter,and fully absord new technologies about electromechanical meter from domestic and abroad,the meter completely accord with relevant technical requirement of class 2 single phase active energy meter stipulated in international standard IEC62053-11, Electromechanical KWH Metercan actually 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 counter.It has following features:High overload,power loss,long-life,specious appearance,etc.
Function & Features
1.Front board three fixed installation ,the cover is made of PC material which is transparent and anti-UV molded overall,the base of the meter is made of quality steel which is after double-through antirust processing,and terminal block made of quality bakelite material which is moisture-resistant,fire-retardant,high temperature molded overall.
2.The meter adopt magnetic bearing .It has following features:Small abrasion,long life and minimal friction,etc.
3.Standard configuration 6 digits display by drum wheel mechanical counter, you can select 7 digits display by drum wheel mechanical counter
4.Measuret three phase four wire active energy consumption.Complying with standard IEC62053-11.
5. Direct connection or CT connction.
6.Extended terminal cover has better protection functions.
