Delivery options to:
Choose countryThe Shelly Pro 2CB C63 is a smart 2-pole circuit breaker for electrical circuit protection and remote switching. It has a 63 A rated current, a C-type trip characteristic and a rated short-circuit breaking capacity of 6 kA.
Protection and voltage monitoring
It protects against overloads, short circuits, overvoltage and undervoltage. The built-in voltmeter measures mains voltage with ±5% accuracy. It does not measure current, power or energy consumption.
Connectivity and control
- Connections: Wi-Fi 2.4 GHz, Bluetooth 4.2 and Ethernet via RJ45.
- Automation: Shelly Smart Control app, schedules and automation scripts, with MQTT, HTTP and WebSocket support.
- Control restriction: a built-in safety switch lets you disable remote control.
- Event history: up to 100 entries for reviewing device operation.
The breaker mounts on a DIN rail and uses a 230 V AC, 50 Hz supply. Its minimum operating voltage is 160 V AC, and the housing measures 93 × 54 × 76 mm.
