Product Overview

What This Model Does

The 4P Tuya Smart WiFi Circuit Breaker is a four-pole breaker for AC 400V three-phase circuits that maintains conventional overload, short-circuit and isolation protection while adding remote switching over WiFi. It operates on AC 50/60Hz, covers rated currents from 16A to 125A, and is compliant with GB10963.1 and IEC60898-1. It pairs with the Tuya SmartLife app to enable remote on/off, timing, delay and cycle switching from any location with internet access. For installers and system integrators, it eliminates the need for site visits to reset tripped breakers and allows smart control of high-current devices without additional controllers.

Key Benefits

  • Enables remote on/off, timing, delay and cycle switching of three-phase circuits from any location with internet access
  • Maintains mechanical overload, short-circuit and isolation protection independent of network status
  • Smart reclosing automatically restores power after a trip, reducing site visits for unattended equipment
  • Replaces separate timers, contactors and PLCs by integrating switching logic into the app
  • Supports Amazon Alexa, Google Home and IFTTT for voice and scene-based control without extra hardware
  • Manual operation and a safety switch remain functional during network outages

Who It Is For

  • Electrical wholesalers adding smart circuit breakers to their conventional MCB product line
  • Panel builders specifying remote-controlled outgoing circuits in distribution boards
  • Facility and property managers overseeing breakers across scattered or remote sites
  • Smart home and building automation brands sourcing a Tuya-compatible breaker for integration
  • Solar and pump installers needing timed or cycled switching without a separate PLC

Problems It Solves

  • An engineer must travel to site simply to reset a tripped breaker after a nuisance trip
  • Timers and contactors add extra components and wiring to achieve scheduled switching
  • Tenant or seasonal supply cannot be switched off without physical access to the distribution board
  • Loads continue running outside operating hours because no one is present to switch them off
  • Smart home projects stall when the electrical panel lacks a controllable switching device

Application Scenarios

  • Street lighting circuits controlled by daily timers instead of astronomical clocks
  • Farm irrigation and water pumps cycled remotely across a growing season
  • Rental housing and student dormitories where power supply is switched per tenancy
  • Municipal works and enterprise sites with breakers distributed across multiple buildings
  • Water heaters and floor heating systems scheduled to run during off-peak hours

Comparison

How It Compares

Conventional MCBSame protection function but adds remote and scheduled switching at a higher unit cost
MCB plus separate timer and contactorOne DIN device instead of three, though switching logic then lives in the app rather than in the panel
Zigbee smart MCBConnects straight to WiFi with no gateway, but depends on the site router being up

Use Guide

  1. Switch on manually and confirm the breaker holds under normal load before pairing
  2. Link the device to Alexa, Google Home or IFTTT if voice or scene control is required
  3. Set timing delay or cycle schedules in the app for automated switching
  4. Keep the manual handle accessible so the circuit can always be isolated on site

FAQ

Questions About the 4P Tuya Smart Wifi Circuit Breaker

What rated currents are available for the 4P 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.
