Installation Notes:

Only used under L-N 220 VAC Wire Connection

CT (Current Transformer) models may be available for higher current ranges.

Standard Connection (Without CT): Recommended continuous load ≤30A, with short-term peaks ≤100A.

High-Current Applications (Maximum Current 100A): External current transformers (CTs) must be used. The electrical meter measures high current indirectly via CTs.

Typical Applications:

Residential energy monitoring

Small business power tracking

Electrical sub-metering

Load management systems

Compliance Information:

This DIN-rail Kilowatt Hour kwh Meter is designed for AC circuits only.

It is recommended that the kilowatt meter be installed in the electric meter box.

For optimal performance and safety, we recommend installation by a qualified electrician professional installation.
