The PST-TOQCB2-2P is a Tuya-native 2-pole (2P) Wi-Fi Smart Circuit Breaker designed for standard 35mm DIN-rail installation. Engineered as a smart Miniature Circuit Breaker (MCB), it acts as an intelligent mains switch or dedicated appliance controller that protects against hardware overloads while feeding real-time energy analytics back to your smartphone. It connects directly to your 2.4GHz home Wi-Fi network without requiring an external automation hub.
Core Capabilities
- Real-Time Energy Metering: Continuously tracks and logs grid parameters, including active power consumption, total line voltage, live current draw, and internal device operating temperatures.
- Adjustable Overload Safety: Features highly customizable safety thresholds via the mobile application, automatically tripping the internal mechanical relay if your system detects over-voltage, under-voltage, overcurrent, or excessive power draws.
- Automatic Reclosing: Programmed to automatically restore power lines after a temporary electrical fault (like a brief grid surge) settles back within safe operating parameters.
- Ecosystem Automation: Syncs natively with the Smart Life and Tuya Smart applications, allowing you to establish cloud timing loops, countdown triggers, and voice-assisted controls via Amazon Alexa or Google Home.
