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. Passive pulse output, impulse indicator light will flicker while the meter is working.
3. Phase loss LED light indicator
4. 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.
5. Meter width is only 122mm. 35mm DIN-rail installation. Similar shape as 7P breaker.
6. All connection lines are incoming and outgoing at the bottom.
