• How do I pair my DewinLVD smart breaker with WiFi?

  Most DewinLVD smart devices are compatible with the Tuya Smart or Smart Life app. To pair, ensure your phone is connected to 2.4GHz WiFi, open the app, and hold the pairing button on the device (often for 5-10 seconds) until the WiFi indicator blinks rapidly.

• What acts as the protection mechanism in DewinLVD automatic reclosing breakers?

  These devices detect leakage or unstable voltage. If a trip occurs due to a temporary fault, the device waits for a short interval and attempts to automatically re-close the circuit, restoring power without manual intervention if the fault has cleared.

• How do I reset the cumulative energy reading on the KWS-303 meter?

  On most digital panel meters like the KWS-303, you can reset the accumulated energy (kWh) data by pressing and holding the designated 'Menu' or 'Reset' button for several seconds while viewing the energy page.

• Can DewinLVD meters measure 3-phase power?

  Yes, DewinLVD offers specific models (such as the LSXDB030 or JLS-E-4T) designed for 3-phase 4-wire systems. Always verify the model specifications before installation to ensure it matches your electrical grid setup.
