The TOMZN TOB9-VAP 63A 1P+N WiFi Smart Circuit Breaker is an all-in-one intelligent electrical protection and energy management device designed for residential and light commercial applications. It supports an adjustable rated current of 1A–63A, operates across AC 90V–300V, and uses 2.4GHz WiFi for remote control through the Tuya Smart and Smart Life apps. The compact DIN-rail mounted breaker provides comprehensive protection against over-voltage, under-voltage, over-current, short circuits, and excessive power consumption, with automatic recovery when electrical conditions return to safe levels. It also offers configurable relay state memory, allowing the device to remain ON, OFF, or return to its previous state after power restoration. Through the mobile app, users can monitor real-time voltage, current, power, and cumulative energy consumption (kWh), while built-in scheduling, countdown, cycle timers, and prepaid energy quota functions provide advanced automation and energy management. The breaker is also compatible with Amazon Alexa and Google Assistant for convenient voice control and is designed for long-term operation with high mechanical endurance. For safe installation, the electrical supply should enter through the top terminals and exit through the bottom terminals, using a Live + Neutral (L+N) configuration only; improper multi-phase or Live-to-Live connections can cause serious damage to the device.
