Tuya Smart Circuit Breaker

The Tuya Smart Circuit Breaker (catalogued under models including the ZJSBL7-100Z series) is a DIN-rail mounted smart switch and energy meter designed for installation inside electrical switchboards. According to specifications from the Tuya Solutions Center and Australian retailers such as HenracTech, the unit provides automated switching, scheduling, and live power monitoring for individual sub-circuits. It tracks real-time electrical metrics including line voltage, load current, active power in kilowatts, and cumulative kilowatt-hours via the Tuya Smart or Smart Life applications without requiring a paid subscription.

Who it suits

This unit suits homeowners who want granular, circuit-level power monitoring or scheduled remote switching for dedicated domestic loads, such as electric water heaters, pumps, or sub-distribution runs. It also fits users managing mixed smart-home environments that rely on Google Home, Amazon Alexa, SmartThings, or Home Assistant for dashboard control. Because specifications confirm 1-pole and 2-pole variants spanning current ratings between 16A and 100A, it accommodates various circuit capacities. Conversely, renters should skip this device because it requires physical alterations to switchboard wiring. It is also unsuitable for households committed to Apple Home or Matter ecosystems, as neither platform is supported.

Australian notes

The hardware is rated for nominal 230V AC (50/60 Hz) operation and is designed to fit standard 35 mm DIN rails found across Australian electrical enclosures. Because this module connects directly to mains wiring, installation is generally work for a licensed electrician; check your state or territory electrical safety regulator for local requirements. Retailer guidance notes that these units typically function as remote smart switches rather than certified primary protection devices, meaning they should not replace dedicated residual current devices (RCDs) or primary circuit breakers.

For local network connectivity, the breaker relies entirely on 2.4 GHz Wi-Fi (802.11 b/g/n) and does not support 5 GHz networks. A reliable wireless signal reaching the switchboard enclosure is necessary for telemetry and app switching; if network connection fails, physical manual toggles must be used.
