Restore Power Automatically After Temporary Trips
The MT53 Series auto-reset RCCB helps restore power following temporary leakage-related trips caused by weather disturbances, grid fluctuations, or other transient conditions. It reduces the need for someone to visit the site simply to reset the RCCB manually.
If the circuit condition does not allow safe restoration, the system will not continue resetting indefinitely.
Remote Control from Anywhere
Connect the MT53AW to the Tuya platform to check circuit status and operate the RCCB remotely through a mobile app. Users can switch the circuit ON or OFF and create timer schedules according to the application. Also, you can choose MT53AI (I/O control version) or MT53AS (RS485 control version) to meet different requirements.
This provides greater visibility and control for homes, shops, solar systems, EV chargers, and other locations where immediate on-site access may not be possible.
Three Reset Attempts with Progressive Delays
The MT53 Series auto-reset RCCB provides three automatic reset attempts. The waiting time increases after each unsuccessful attempt, with typical intervals such as 10, 30, and 60 seconds.
This progressive process gives temporary electrical conditions time to clear while avoiding continuous reset attempts when the fault remains present.
Compact Upgrade for Existing RCCBs
The 18 mm-wide, side-mounted auto-reclosing accessory can be matched with selected 2P and 4P RCCBs from Matismart and major breaker brands, including Schneider, Chint, Hager, and Eaton. Compatibility should be confirmed according to the specific RCCB model.
