The H81xx Series Energy Meters are easy to install and provide exceptional system accuracy, making them ideal for all submetering applications.
Each meter is factory-matched with one to three split-core CTs. The meter/CT pairs are system-calibrated to provide excellent total system accuracies of 1% from 2% to 100% of the amperage rating of the CTs (e.g., 2-100 amps with 100 amp CTs). Matching serial numbers assure that the meter and CT were calibrated together (matching does not apply if using 100A CTs).
The H81xx is easy to install. The split-core CTs eliminate the need to remove electrical conductors, reducing installation time. The meter is also capable of detecting and correcting phase reversal, eliminating the need for concern about CT load orientation. The convenient color coding of the CTs and voltage leads make correct connection simple.
