About this item
  • [Automatic reclosing function]: Applies to protection against overload, overcurrent, overvoltage, undervoltage and current leakage; if the device attempts to recover automatically or remotely three times within 15 minutes, this function is deactivated. To reactivate it, the switch must be held down for 15 minutes or the power supply must be restarted.
  • [Multiple protection]: The TONGOU residual current circuit breaker (RCBO) combines comprehensive protection functions, including: short circuit, overvoltage, overcurrent, temperature (wide thermal range), overload, undervoltage, current leakage, overcurrent protection, automatic restoration and modern control (remote and voice control). By combining RCD and MCB, the compact design simplifies installation and significantly increases system reliability.
  • [Intelligent remote control]: The intelligent switch supports remote control commands (on/off), voice control via Amazon Alexa/Google Home, parameter configuration via TUYA/Smart Life app, and remote monitoring via iOS/Android, including real-time performance analysis, voltage/current monitoring, active/reactive power measurement, temperature detection, phase angle measurement, switching status display, device diagnostics, frequency measurement, warning messages, event log, and error history.
  • [Installation and connection]: The 1P+N modular switch (36x49x120mm) enables quick mounting on 35mm DIN rails, has screw terminals for secure connections and is easy to install and store thanks to its robust, compact design. The housing is made of self-extinguishing material with high temperature resistance.
  • [SMR1-40JWTA Parameters]: Type A/rated current: 1-40A adjustable (tripping characteristic type C)/fault current protection threshold: 30mA / WiFi control: 2.4 GHz frequency.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
