Product Q&A

Q:What communication methods does this smart circuit breaker support?

It supports Tuya, WIFI, RS485 and Bluetooth, enabling remote switching, status monitoring and fault alerts via APP or platform.

Q:What are the rated current and voltage ranges? What pole configurations are available?

Current ratings from 6A to 100A; single-phase 230V AC (1P+N/2P), three-phase 400V AC (3P/3P+N/4P), 50Hz.

Q:What protection functions does it offer?

It provides overload, short-circuit, over-voltage, under-voltage and loss-of-voltage protection, with optional residual current function and configurable auto-reclosing delay.

Q:Does remote control require constant network connection? How to use Bluetooth and RS485?

WIFI for long-distance remote control. Bluetooth is for short-range pairing and parameter setting. RS485 connects to central control system for unified management. Local operation and protection functions work normally even without network.

Q:Can customized functions or OEM services be provided?

Customization for coil voltage, communication protocols and protection parameters is available, along with OEM/ODM services. Please contact our sales team for details.
