Product Overview
What This Model Does
The 3P Tuya Smart WiFi Circuit Breaker is a three-pole breaker for AC 400V three-phase circuits that maintains standard overload, short-circuit and isolation protection while adding remote switching over WiFi. It is built to GB10963.1 and IEC60898-1, covers 16A to 125A, and pairs with the Tuya SmartLife app so an installer can switch, time or cycle a circuit from anywhere with a data connection. For distributors it is the version customers ask for once they have wired a site and cannot keep sending an engineer to reset a breaker by hand.
Key Benefits
- Turns an ordinary three-phase feeder into a circuit you can switch from a phone anywhere with internet
- Keeps conventional overload short-circuit and isolation protection so it drops into an existing DIN rail
- Smart reclosing removes the site visit after a nuisance trip on unattended equipment
- Timing delay and cycle switching automate pumps floor heating and street lighting without a separate controller
- Works with Amazon Alexa Google Home and IFTTT so it fits the ecosystems customers already run
- Manual operation and a safety switch remain available when the network is down
Who It Is For
- Electrical wholesalers adding a smart range beside their conventional MCB shelf
- Panel builders specifying remote-controlled outgoing ways in distribution boards
- Facility and property managers responsible for breakers across scattered sites
- Smart home and building automation brands sourcing a Tuya-compatible breaker to badge
- Solar and pump installers who need timed or cycled switching without a PLC
Problems It Solves
- An engineer has to travel to site simply to reset a tripped breaker
- Timers and contactors add parts and wiring to achieve scheduled switching
- Tenant or seasonal supply cannot be switched off without physical access to the board
- Loads keep running out of hours because nobody is there to switch them off
- Smart home projects stall when the board itself has no controllable device
Application Scenarios
- Street lighting circuits switched on a daily timer instead of an astronomical clock
- Farm irrigation and water pumps cycled remotely across a season
- Rental housing and student dormitories where supply is switched per tenancy
- Municipal works and enterprise sites with breakers spread across many buildings
- Water heaters and floor heating run on a schedule to shift load off peak hours

Manufacturing Process
- Moulding and machining of the breaker housing and internal carriers
- Assembly of the thermal-magnetic trip unit and contact system
- Fitting and firmware loading of the WiFi control module
- Calibration of the trip characteristic against the Type C curve
- Routine dielectric and operation testing before packing
Customization Options
- Rated current selected from 16A to 125A per order
- Pole count supplied as 1P 2P 3P or 4P from the same series
- ODM branding on housing print and packaging
- Packaging and carton marking to the buyer's own specification
Comparison
How It Compares
| Conventional MCB | Same protection function but adds remote and scheduled switching at a higher unit cost |
|---|---|
| MCB plus separate timer and contactor | One DIN device instead of three, though switching logic then lives in the app rather than in the panel |
| Zigbee smart MCB | Connects straight to WiFi with no gateway, but depends on the site router being up |
Use Guide
- Switch on manually and confirm the breaker holds under normal load before pairing
- Link the device to Alexa Google Home or IFTTT if voice or scene control is required
- Set timing delay or cycle schedules in the app for automated switching
- Keep the manual handle accessible so the circuit can always be isolated on site

FAQ
Questions About the 3P Tuya Smart Wifi Circuit Breaker
What rated currents are available for the 3P version
The series covers 16A, 20A, 25A, 32A, 40A, 63A, 80A, 100A and 125A, with a 125A rack rating.
Does it still protect the circuit if the internet goes down
Yes. Overload, short-circuit and isolation protection are mechanical and work independently of the network. Only remote control needs a connection.
Which app and voice platforms does it work with
It runs on Tuya SmartLife and supports Amazon Alexa, Google Home and IFTTT.
What standards is it built to
GB10963.1 and IEC60898-1, with a Type C instantaneous trip and 6KA rated short-circuit breaking capacity.
Can we have it supplied under our own brand
Yes. We run ODM projects and can print your branding on the housing and packaging. Send us your artwork and the current ratings you need.
What temperature range can it be installed in
The specified use temperature is -25 degrees C to +65 degrees C at IP20 protection, so it belongs inside an enclosure.
What are the minimum order quantity and lead time
Both depend on the current ratings and branding you need. Email [email protected] with your model list and quantities for a current answer.
