Description
These two types of electricity meters are used to measure three phase four wire AC active energy. They are made by SMT (Surface mounting technology) process and conform to the standards of IEC62053-21 and IEC62052-11.

Features
1. Active energy is measured bi-directionally and reverse electricity will be measured and counted into total electricity.
2. Reverse electricity will be measured. Reverse indicator light available.
3. Passive pulse output, impulse indicator light will flicker while the meter is working.
4. Phase loss LED light indicator
5. Measurement for phase loss. The metering precision will not be influenced if any one phase or two phases of three phase four wire meter cut off.
6. While power cut, all storage data will not lose and can be saved for more than 15 years.
7. Meter width is only 70mm. 35mm DIN-rail installation. Similar shape as 4P breaker.

Optional Function
Real time electric quantity, three phase current, voltage, positive energy, reactive energy, energy factor and frequency measurement and display (D3403 only)
