Smart 1-Pole 125A Circuit Breaker | Tuya Smart Life
The Smart 1-Pole 125A Circuit Breaker is a specialized electrical component that combines the safety of a traditional circuit breaker with the connectivity of a smart home device. Unlike a smart plug or relay, this device is installed directly onto your main distribution board (DB) or consumer unit.
Product features
- Dual function design: the breaker serves two primary purposes in one unit:
- Safety (MCB): it provides standard overload and short-circuit protection. If the current exceeds 125A or a fault occurs, the breaker trips mechanically to protect the wiring and prevent fires.
- Smart control: it features an internal motorized mechanism that allows you to switch the circuit on or off remotely via the Tuya app, even if you are not at home.
- Voice control: fully compatible with Amazon Alexa and Google Assistant for hands-free operation.
- Safety interlocks: features a physical toggle switch for manual override and often includes a safety lock feature in the app to prevent accidental remote switching during maintenance.
- Scheduling and timers: set “on” and “off” routines on the smart app.
