Shelly Pro 2CB C10 smart circuit breaker, 2-pole, 10 A
Delivery options to:
Choose countryThe Shelly Pro 2CB C10 is a smart miniature circuit breaker for DIN-rail installation in an electrical panel. It disconnects phase and neutral together (L+N), with a 10 A rated current, C trip characteristic and 6 kA short-circuit breaking capacity.
Protection and switching limits
A thermal-magnetic mechanism trips the circuit in the event of an overload or short circuit. Electronic overvoltage and undervoltage protection offers configurable thresholds and response delays. A physical safety switch can disable electronic control, including remote switching and the voltage protection functions implemented by the control unit.
Remote re-engagement is possible only after remote disconnection. A protective trip or manual switch-off requires on-site intervention. Remote switching must occur less than once per minute.
Monitoring and automation
- Connectivity: 2.4 GHz Wi-Fi, Bluetooth 4.2 and wired RJ45 Ethernet.
- Control: Shelly Smart Control app and a built-in web interface; basic local functions can operate without an additional control hub.
- Monitoring: voltage measurement with ±5% accuracy, internal temperature monitoring, event history and notifications for selected events.
- Automation: schedules, scripts, webhooks and virtual components, plus CSV and JSON data export and OTA updates.
The front panel has a manual lever, reset button and LEDs for network connection and software updates. The mechanical indicator is green when the circuit is open and red when it is closed.

Can the breaker be switched back on remotely after a protective trip?
No. Remote re-engagement is possible only if the circuit was previously disconnected remotely. A protective trip or manual switch-off requires on-site intervention.
Does it need an additional control hub?
Basic local functions can operate without an additional control hub. The Shelly Smart Control app and a built-in web interface are available for control.
