## Summary description

GreenBlue GB364 E is a plug-in energy meter (wattmeter) for monitoring AC mains consumption. It operates at 220–240V AC, 50Hz with a maximum load of 16A and IP20 protection. The device records real-time power, cumulative energy usage and includes a built-in battery for retained settings. Suitable for home and small office power monitoring and load checks.

## Long description

GreenBlue GB364 E is a compact plug-in energy meter designed for monitoring mains electricity consumption in homes and small offices. The wattmeter measures real-time power and cumulative energy consumption on standard 220–240V AC, 50Hz circuits and supports loads up to 16A. An IP20 enclosure suits indoor use, and a built-in battery preserves settings and recorded cumulative values when mains power is interrupted.
Advantages
The device provides continuous measurement of active power and total energy consumption with a simple plug-and-play design that requires no additional wiring. Its compact form factor allows easy installation between wall outlets and appliances. IP20-rated housing is appropriate for protected indoor environments, and the internal battery maintains user settings and accumulated data during brief power outages.
Suitable for
Monitoring electricity usage of household appliances such as refrigerators, TVs, computers and heaters
Assessing power consumption in small office equipment and workstations
Performing quick load checks to identify high-consumption devices
Estimating running costs and verifying energy-saving measures
When it may not be suitable
Because the GB364 E is IP20-rated, it is intended for indoor use only and should not be used in wet, dusty or outdoor environments. The meter supports a single-phase mains supply at 220–240V AC, 50Hz and a maximum continuous current of 16A; it is not suitable for three-phase installations or for loads that exceed the rated current.
Key specifications
Supply voltage: 220–240V AC, 50Hz
Maximum load/current: 16A
Measured values: real-time active power and cumulative energy (kWh)
Protection class: IP20 (indoor use)
Power retention: built-in battery for settings and cumulative values
Form factor: plug-in wattmeter, compact housing
How to use
Plug the GreenBlue GB364 E into a standard wall outlet and connect the appliance to be measured into the meter's socket. The display will show real-time power consumption and accumulated energy usage automatically. Use the device controls to view cumulative kWh values and to access available display modes. The built-in battery keeps settings and accumulated readings when mains power is removed; reconnecting mains resumes measurement and updates totals.
What to consider before purchase
Confirm that your supply is single-phase 220–240V AC at 50Hz and that the monitored load does not exceed 16A.
Use only in indoor, dry, and protected environments due to IP20 protection.
If you need monitoring for multiple circuits, three-phase systems, or outdoor installations, consider a different meter model suited to those conditions.
Usage recommendations
For reliable results, place the meter on a dedicated outlet that is free from frequent plug switching and avoid connecting multi-socket extension leads that may introduce additional losses. Record baseline readings before and after testing appliances to accurately compare consumption, and periodically check the device for signs of damage or overheating when measuring high-draw loads near the 16A limit.
