TOP 0.66

Current transformers TOP 0.66 are intended to transmit signal of measuring information to meters (ammeters, wattmeters, phase meters, counters) in AC installations of 50 Hz with rated voltage of up to 0.66 kV, inclusively. As well as they are used in the measuring diagrams of low-voltage meters of building and structures, in power transmission and distribution diagrams including inside other articles and they are intended for revenue metering
The transformers are provided with two contacts of secondary winding, transparent cover protecting secondary winding clamps and data sheet. There is the possibility to set seals excluding the access to the secondary winding clamps and data sheet after mounting.
