WattNet-3R DIN-Rail Relay Meter Monitor
Combine energy metering with a DIN-rail relay output. The switching function needs its own load and control-circuit assessment, separate from the CT measurement range.
Before you order Available to order.
Review the system and installation requirements before ordering. Guides and support can help you prepare; they do not approve an installation.

Resolve fit before ordering.
The supplier drawing labels body and projection dimensions separately. Use the manual's overall dimensions and have a qualified installer confirm enclosure clearance and the controlled equipment's requirements.
A larger CT option does not increase the 16 A relay output rating. These documented specifications do not approve a particular load, supply arrangement or installation.

Does a CT rating define relay capacity?
- 01
What it measures or controls
No. A CT measures current; the relay controls a circuit. A larger CT option does not authorize switching a larger load. Have the installer assess the documented relay output, controlled equipment and DIN-rail space separately.
