black color 1 phase single phase electromechanical watt-hour meter electricity kwh meter
Single phase kwh measuring meter
Function and features
1.Front board three fixed installation ,the cover and the bease are made of bakelite material t,and terminal block made of quality bakelite material which is moisture-resistant,fire-retardant,high temperature molded overall.
2.Voltage components and current components are used of double insulation structure,has good electrical characteristics.
4.The 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.
5.All kinds of adjustment mechanism adopt no step shifting mechnism.The meter starting and creeping needn to be adjusted which is finished by anti-creeping hole of disc and convenient for adjusting by users.
6.Standard configuration register display by drum wheel mechanical counter, you can select 5+1 or 4+1 digits display by drum wheel mechanical counter
7.Single component measurement single phase two wire active energy consumption.Complying with standard IEC62053-11.
9.Can select short terminal cover or extended terminal cover.
