Where you'd use it
Original Shelly EM Spare
Keep one as a spare or replacement clamp for an existing original Shelly EM installation, since it's not compatible with the Gen3 version.
Legacy Installation Expansion
Add a second monitored circuit to an older Shelly EM setup that's already in service, using its unused second channel.
Circuit-Specific Metering
Clamp it around a single circuit rated up to 50A, such as a shower or oven feed, to isolate its consumption from the rest of the board on an existing EM.
