2P 40A 300mA Type AC Residual Current Circuit Breaker with Automatic Reclose, AC230V, RCCB Automatic Closing, Intelligent Circuit Breaker, GYAR9-AC-G

【Intelligent Automatic Re-close】: This automatic circuit breaker automatically closes the gate when the RCCB (Remote Controlled Circuit Breaker) trips accidentally, eliminating the need for manual closing. This reduces manual maintenance costs, corrects errors promptly, and improves efficiency.
【Automatic/Manual Switching】: In AUTO mode, automatic re-closes the gate after a fault. In MANU mode, the gate must be manually reset after a fault. After the "LOCK" button is opened, the gate cannot be closed to protect electrical safety and prevent accidental contact.
【Self-locking Mode】: After a circuit failure, this intelligent circuit breaker automatically closes the gate after 9 seconds for the first trip, 59 seconds for the second trip, and 299 seconds for the third trip. After the fourth failure, the recloser enters self-locking mode, and it is necessary to check the circuit's safety before manually reopening the gate. [Digital LED Display]: AUTO Mode: Red flashing indicates gate opening, green flashing indicates gate closing; MANU Mode: Yellow light is always on for manual gate opening and closing. The code breaks to indicate the number of openings and closings, as well as the countdown timer for reclosing.
【Wide Application】: The automatic reclosing smart gate can be widely used in grid-connected photovoltaic AC distribution boxes, as well as in unattended mobile phone base stations, elevators, smart homes, smart factories, new energy vehicle charging stations, etc.
