Auto Reclose
While the resi dual current exceeds action current value gear and trip, the device will auto reclose after 20-60 seconds, while manually reclose is not imited. The device reclosed for 5 seconds and the circuit taulty disappeared. it reclose successtully, and the breeker runs nomally; Otherwise. the device will trip and lock itl circult tauly not removed, The device won’ t aulo feclose and requires manually operation to teclose.
Over voltage Protection
While the line voltage is higher than the setup protection value, the breaker will trip. While the line voltage recovers to normal, the breaker will auto reclose and run. The voltage satup value range is. 250-300V. normally, setup 280V while manufacture. The customer can set up or clase this protecton as needed.
Under vltage Potectin
While the line vllage is lower than the setup protection value,the breaker will trip.While the line vllage recovers to normal,the breaker will auto reclose and run.The vltage setup value range is 150-200V.normally setup 170V while manufacture,The customer can set up or close this protection a8 needed.
Phase Loss Protection
While the line terminal has phase loss, the breaker will trip. The breaker will auto reclose and run while the phase loss clrcult faulty disappears.
Interink Communication Protection
This device may connect with other fire extinguishing equipment and owns protection as below.
