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

【Intelligent Automatic Reclosing】: The Type A circuit breaker has various electrical signal options: sinusoidal AC, pulsed DC, and pulsed half-wave + DC, allowing for wider application and stable performance. It automatically closes the circuit breaker when the RCCB trips accidentally without manual resetting, reducing manual maintenance costs, correcting faults promptly, and improving efficiency. 【Automatic/Manual Switching】: In AUTO mode, the 40A circuit breaker can automatically reset after a fault. In MANU mode, manual reset is required after a fault. After the "LOCK" button is opened, the closing operation cannot be performed to protect electrical safety and prevent accidental contact.
【Self-Locking Mode】: Automatic recloser after a circuit failure. The circuit closes automatically after 9 seconds for the first failure, 59 seconds for the second, and 299 seconds for the third. After the fourth failure, the recloser is in self-locking mode, and it is necessary to check the circuit's safety before manually reopening the gate.
【Digital LED Display】: Automatic closing circuit breaker in AUTO mode: flashing red indicates gate opening, flashing green indicates gate closing; in MANU mode: the yellow indicator light is always on for manual opening and closing of the gate. 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.
