Description
SHELLY Pro 3CB C63 Circuit Breaker
The SHELLY Pro 3CB C63 circuit breaker is a smart, 3-pole electrical circuit protection device with a rated current of 63 A, a C-type trip characteristic, and a short-circuit breaking capacity of 6 kA. The device protects the electrical system against overloads, short circuits, and excessively high or low voltage. Thanks to Wi-Fi, Bluetooth, and Ethernet connectivity, it allows for remote activation and deactivation of the circuit, as well as measurement and monitoring of line voltage (V) using a built-in voltmeter. Support for the Shelly Smart Control app, schedules, automation scripts, and the MQTT protocol enables integration with smart home and building management systems. A built-in safety switch allows you to disable remote control, and an event history of up to 100 events makes it easy to monitor the operation of the safety feature.
