Description
This meter is designed to measure single phase three wire AC active energy and perfect for the secondary circuits with flat rate tariff or single phase electric equipment with narrow interior space. Made by SMT (Surface mounting technology) manufacturing process, the meter is in accordance with standard IEC62053-21.

Features
1. Active energy is measured bi-directionally and reverse electricity will be measured and counted into total electricity.
2. Power indicator light
3. Passive pulse output, conform to DIN43864 standard
4. Width of the meter is only 78mm. 35mm DIN-rail installation. Similar shape as 4P breaker.
5. All connection lines are incoming and outgoing at the bottom.
