Automatic reclosing function

When there is undervoltage protection: After tripping due to overvoltage or undervoltage, it meets the closing conditions and closes after a 30 second delay

After leakage tripping, it will automatically reclose once with a delay of 30 seconds. If unsuccessful, delay for 15 minutes for the second reclosing. If unsuccessful, delay for 15 minutes for the third reclosing. If unsuccessful, enter the locked state and no longer reclose. To eliminate the leakage fault, press and hold the [Test] button for more than 3 seconds to unlock or manually close

Load short circuit or overload tripping or manual disconnection, entering the locked state, troubleshooting is required, press the 【 Test 】 key for more than 3 seconds to unlock or manually close the circuit

Remote local switching

You can choose between remote or local priority. Remote control fails when in the 'Local' position. When in the 'Remote' position, a remote disconnection signal is given, the circuit breaker opens, and the automatic reclosing function fails; Give remote closing signal, close the circuit breaker, and restore all functions

Closing prompt function

Flashing power light prompt before closing

Security padlock

When in the open state, it can be locked with a locking diameter of Φ 4-6mm

communication

Standard RS485 communication interface, in compliance with DL/T "Residual Current Operated Circuit Breaker Communication Protocol" requirements; Can achieve remote control, capable of intelligent management such as opening, closing, and querying operation status from a distance
