Shelly Pro 3CB C10 smart 3-pole circuit breaker, 10 A
Delivery options to:
Choose countryThe Shelly Pro 3CB C10 is a smart 3-pole circuit breaker rated at 10 A, with a C tripping characteristic and 6 kA short-circuit breaking capacity. Designed for residential and commercial electrical installations, it combines circuit protection with local and remote control.
Protection and monitoring
The breaker disconnects power in the event of an overload or short circuit and provides overvoltage and undervoltage protection. Voltage monitoring responds when configured thresholds are exceeded. An event history stores up to 100 entries, including manual and remote switching operations and protection trips.
- Connectivity: 2.4 GHz Wi-Fi, Bluetooth 4.2 and Ethernet through an RJ45 port.
- Control: the Shelly Smart Control app and a built-in web interface for configuration and monitoring on the local network.
- Automation: schedules, scripts, MQTT and webhooks.
- Indicators: connection-status LEDs and a mechanical contact position indicator.
Reactivation and installation
Remote reactivation is possible only after a previous remote switch-off, not after a protection trip or manual disconnection. A mechanical lever and a safety switch that locks out electronic control are provided for maintenance. The device mounts on a DIN rail in an electrical panel, measures 93 × 72 × 76 mm and requires a 230 V AC supply.

Can the breaker be switched back on remotely after a protection trip?
No. Remote reactivation is possible only if the circuit was previously switched off remotely. It is not available after a protection trip or manual disconnection.
How can the device be controlled and configured?
It supports local and remote control through the Shelly Smart Control app and a built-in web interface on the local network. Connectivity includes Wi-Fi, Bluetooth and Ethernet, while schedules, scripts, MQTT and webhooks support automation.
