## Summary description

Nous D4Z is an energy monitor with ZigBee connectivity that uses three 120A current clamps for measuring three‑phase electrical circuits. It provides real‑time monitoring of current and energy consumption for residential or small commercial installations, enabling usage tracking, load balancing and efficiency analysis via a compatible ZigBee gateway or smart home hub.

## Long description

Nous D4Z ZigBee 120A 3‑phase current clamps is an energy monitor designed to measure three‑phase electrical circuits using three separate 120A current clamps and ZigBee wireless connectivity. The device provides real‑time monitoring of current and energy consumption for residential and small commercial installations. Data from the monitor can be transmitted to a compatible ZigBee gateway or smart home hub for visualization, logging and further automation.
Advantages
The compact clamp‑based design allows installation without interrupting existing wiring, enabling non‑invasive current measurement. ZigBee connectivity supports low‑power wireless transmission and integration with a range of smart home systems that accept ZigBee devices. With three dedicated clamps, the monitor tracks each phase independently, which helps identify unbalanced loads and supports basic load‑management and efficiency analysis. The monitor is suitable for continuous measurement and provides timely data for energy tracking and troubleshooting.
Suitable for
Monitoring energy consumption in residential three‑phase supply installations
Small commercial sites with three‑phase circuits such as workshops or small offices
Detecting phase imbalance and assessing load distribution
Integration with ZigBee smart home hubs for logging and automation
Key specifications
Measurement method: three external current clamps for each phase
Clamp rating: 120 A per clamp (AC)
Supported circuit type: three‑phase AC systems
Communication: ZigBee wireless protocol for integration with compatible gateways and hubs
Data provided: real‑time current and energy usage per phase
Installation: clamp‑on (non‑invasive) current measurement
How to use
Install each 120A current clamp around the conductors of the three phases, ensuring the clamps are placed on the correct individual phase conductors and oriented according to the manufacturer’s polarity markings. Connect the monitor to power if required by the specific model instructions and follow the pairing procedure to add the device to a ZigBee gateway or smart home hub. Verify readings in the hub or companion app and allow the system to calibrate during initial operation. Confirm that the clamps do not contact bare conductors and secure them to avoid movement.
Usage recommendations
Use the monitor only on circuits within the clamps’ 120A rating and follow local electrical safety regulations. For reliable integration, pair the device with a ZigBee gateway or hub that supports energy monitoring devices. Periodically inspect clamps and connections for wear or loosening and consult a qualified electrician for installation assistance when working near live wiring.
