Delivery options to:
Choose countryThe Shelly Pro 4CB C10 is a smart 4-pole circuit breaker rated at 10 A, with a C tripping characteristic and 6 kA short-circuit breaking capacity. It protects residential and commercial electrical installations against overloads, short circuits, overvoltage and undervoltage.
Monitoring and automation
- Connectivity: Wi-Fi, Bluetooth and Ethernet, with status checks and remote power disconnection through the Shelly Smart Control app.
- Automation: schedules, scripts, MQTT and webhooks support custom control scenarios.
- Event history: up to 100 records of manual and remote switching and protection trips.
- Local access: a built-in web interface for configuration and parameter monitoring on the local network.
Control and installation
Remote reactivation is possible only after a remote disconnection, not after a protection trip or manual disconnection. A mechanical lever and safety switch allow electronic control to be locked out for maintenance. LEDs indicate connection status, while a mechanical indicator shows contact position.
The breaker mounts on a DIN rail in an electrical panel. It measures 93 × 90 × 76 mm, uses a 230 V AC supply and has an RJ45 Ethernet port.

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.
Can it be configured on a local network?
Yes. The built-in web interface allows configuration and parameter monitoring directly on the local network.
