CQB7ZNM-80 WIFI Circuit Breaker Smart Circuit Breaker
Le CQB7ZNM-80 is specified for overload, short-circuit, leakage and voltage monitoring functions. Select it using the published voltage, current, pole and protection data, then confirm conductor coordination, fault conditions, enclosure requirements and local installation rules.
Vue d'ensemble du produit
CQB7ZNM-80 is a WiFi smart circuit breaker for 230/240V AC applications. It is intended for connected residential or light-commercial circuits where local protection remains independent of the app; this describes an evaluation context, not a universal approval. Confirm the complete circuit design before specifying the product.
overload, short-circuit, leakage and voltage monitoring functions is distinct from adjacent protection functions. Do not infer AC/DC suitability, residual-current protection, automatic control or isolation performance from the product family name alone.

CQB7ZNM-80 Product FAQ
What is the CQB7ZNM-80 used for?
The CQB7ZNM-80 is specified for overload, short-circuit, leakage and voltage monitoring functions in 230/240V AC applications, within the ratings and configurations listed in its technical table. Final suitability depends on the complete circuit design.
What can the CQB7ZNM-80 smart function control?
The published page describes WiFi monitoring and remote control through Smart Life/Tuya. Confirm network availability, permissions, local override, outage behaviour and the independent operation of the protective function.
How do I choose the CQB7ZNM-80 rating and poles?
Start with the design current and system arrangement, then choose only a published option. The page lists pole options as 1P+N; confirm neutral, polarity, conductors and isolation requirements.
What safety limitation applies to the CQB7ZNM-80?
Do not treat the CQB7ZNM-80 as a universal substitute for another device. Confirm C curve; AC residual-current type listed, the system voltage, fault or leakage conditions and any separate upstream protection before selection.
Can the CQB7ZNM-80 be used in another circuit type?
Only when the exact ordered configuration is rated for that circuit. AC and DC duties, residual-current devices, isolators, smart controls and voltage protectors are not interchangeable by appearance or current rating.
How should the CQB7ZNM-80 be installed and tested?
Use the exact product drawing, terminal identification and instructions. A qualified person should verify isolation, conductors, torque, settings, coordination and functional tests before energising the circuit.
