80A Current Transformer
The higher-range transformer for a Shelly EM Gen3, for circuits up to 80 A. Solid core, so the cable threads through it.

Everything you need to know
An EM Gen3 measures to 80 A, but the clamp in its box is rated to 50 A. This is the transformer that covers the rest of that range. It is a different shape to the 50A clamp: the core is solid rather than hinged, so the conductor passes through the ring instead of the ring closing around it.
What is a Shelly energy meter?
A Shelly energy meter measures the power a circuit is using. It shows how much that circuit is using right now, keeps a running total of how much it has used over time, and stores one-minute records on the meter itself. It does not turn anything on or off, so every switch and appliance on the circuit works exactly as it did before the meter went in. You see the numbers in the Shelly app, or in Home Assistant through its Shelly integration, with no Shelly account in the middle.
Power usage
See where the power goes
Clamp the mains where they land in the switchboard and you see what the whole house is using, right now and over time. Put a meter on a single circuit, like the hot water or the air conditioner, and you see what that one thing costs to run.
Automations
Switch a load off when it runs high
An automation can run when a circuit climbs past a figure you set, like turning a heater off during a high tariff window. The meter supplies the reading, and a relay or a contactor does the switching. The EM Gen3 and Pro EM-50 have a built-in output for driving a contactor.
Solar
Import and generation, separately
One channel on the mains and one on the solar circuit gives you what you imported and what your roof made, as two separate numbers. A single channel nets them together and hides both. The clamp reads the current in the cable, so the meter works the same whoever made the panels or the inverter.
Alerts
Know when something finishes or fails
When a circuit drops to nothing, whatever was running has finished, so an automation can tell you the washing machine is done. An old fridge or a pool pump drawing more than it used to is often the first sign it needs a service.
Getting started
1
Start with what you want to know Start here
One appliance, or the whole house? A single circuit you can reach in the wall is an EM Mini Gen4 job. The EM Gen3 clamps up to two circuits, or the mains of a single phase house. For something more substantial that lives in your switchboard, look at the Pro range, which clips onto the DIN rail.
2
Add more as you go Then
Each meter works independently, so you can start with a single circuit and add more as you need them. They don't need to match: mix models and generations, and they sit side by side in the Shelly app or Home Assistant.

The Shelly EM Gen3. Shelly do not list it for the Pro EM-50.
The opening is 7 mm across. Measure the outside diameter of the insulated conductor before you order, because the cable on an 80 A circuit can be thicker than that.
No. The core is solid, so the cable has to be threaded through the ring. Plan it into work an electrician is already doing rather than as a retrofit onto a live cable.
Only if the circuit draws more than 50 A. The clamp supplied with an EM Gen3 covers anything under that.
