Shelly Pro 3 3-phase dry-contact smart relay for the electrical panel
Shelly Pro 3 3-phase dry-contact smart relay for the electrical panel
Shelly Pro 3 3-channel dry-contact smart relay for 3-phase, 3 x 16 A with a total load of 48 A, for controlling a variety of loads.
Because it’s a dry-contact relay, it can switch AC and DC, as well as three different phases, even ones separate from the supply phase.
Part of Shelly’s innovative product line, it lets you control, monitor and manage electrical circuits, with full readings and control in the app (available in Hebrew). Quick, simple installation, with both wired (Ethernet) and Wi-Fi connectivity.
Typical applications:
- Controlling and monitoring electrical loads
- Shabbat timers
- Air conditioner control
- Controlling and monitoring outlets
- Controlling and monitoring pumps
- Controlling generators and compressors
- Upgrading an older panel-based smart home system to a modern smart home with voice control and simple, self-managed control from the app
- Smart electrical systems, smart home, smart relay, smart switch

Who it’s for
A 3-channel 16 A dry-contact relay for the electrical panel. Dry contact means it can switch a circuit fed from another source: a different phase, low voltage or DC. Suitable for three separate phases, pumps, compressors, gates and old systems being replaced. When you also need power metering on each channel, Pro 4PM is a better fit.
What to know before installing
- Requires space on the DIN rail in the electrical panel.
- Each channel handles up to 16 A.
- It doesn’t measure power use.
- Wi-Fi or Ethernet connection. You can add sensors with Pro Add-on.
FAQ
What is a dry contact?
The relay’s contact isn’t connected to the device’s own supply, so you can switch any circuit through it: a different phase, 24 V or DC.
Can it run a 3-phase motor?
Through a suitable contactor, yes. The relay drives the contactor, and the contactor runs the motor.
Do the wall switches keep working?
Yes. You connect them to the relay’s inputs.
