Smart 4-Pole Energy Monitor 100A Circuit Breaker | Three-phase | Tuya Smart Life
A Smart 4-Pole Energy Monitor 100A Circuit Breaker is a compact, DIN-rail mounted electrical safety device designed to fit into standard distribution boards. It combines the traditional overcurrent protection of a standard circuit breaker with modern IoT capabilities, allowing for remote management, automation, and real-time power analytics.
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 100A 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.
- Real-time monitoring: includes energy metering, allowing you to track:
- Voltage
- Current
- Power consumption
- Supports RS485 communication interface: integrating an RS485 communication port into a smart circuit breaker transitions it from a simple standalone smart device into an industrial-grade, highly reliable networking node.
