Deployment brief

What teams learn before rolling out TUYA Smart Circuit Breaker with Metering.

The SUON STB3-125/WJ Smart Circuit Breaker (C63, 4-Pole) is an industrial-grade smart breaker designed for high-current three-phase + neutral applications. With dual communication support (Wi-Fi + RS485) and Tuya platform integration, it enables remote control, real-time energy monitoring, and advanced automation for industrial, commercial, and high-power residential systems.

Example use

Install the breaker as a main 3-phase feeder to monitor total energy consumption per phase, remotely disconnect loads during faults, and automate shutdowns when current exceeds safe limits.
