The meters COE5028H, COE5028HM are protected on a zero wire.

In the meter is used the modern element base of conducting foreign firms.

In the meter exists of a target signal appropriate to the international standard DIN 43864, allows using it as the primary gauge in the automated systems for the accounting of the electric power.
