Shelly 3EM-63W Gen3 – 3-Phase Smart Energy Meter (Wired Version)

Monitor the energy usage of your entire home, office, or industrial facility with surgical precision. The Shelly 3EM-63W Gen3 is an advanced smart energy meter designed for monitoring a 3-phase electrical system, or three entirely independent single-phase circuits. This is the W (Wire) version, featuring flying lead wires for the phase connections. This provides much-needed placement flexibility inside crowded distribution boards where snapping the unit directly onto a breaker isn't possible.

4-Quadrant Measurement & Solar Ready

This meter doesn't just track basic consumption. Utilizing 4-quadrant measurement (Class B accuracy), it provides real-time data on voltage, current, active power, apparent power, and power factor. This makes it an absolute must-have for homes with Photovoltaic (Solar) installations, as it precisely tracks the electricity pulled from the grid as well as the solar energy injected back into it.

Technical Specifications:

• Device Type: 3-phase smart energy meter utilizing non-invasive split-core current transformers.
