Where you'd use it
Third-Channel Expansion
Add a spare clamp to a Shelly Pro EM or EM Gen3 installation to bring a second circuit, such as a solar diversion feed, into monitoring alongside the main incomer.
Replacing a Damaged Clamp
Swap out a clamp that's been damaged during a rewire or panel change without needing to replace the whole EM Gen3 or Pro EM unit.
Dedicated Circuit Tracking
Fit it around a single sub-circuit, such as an EV charger or heat pump feed rated up to 50A, to isolate its consumption from the rest of the board.
