A9Y83640 SCHNEIDER ELECTRIC

The A9Y83640 is an add-on residual current device (RCD) from the Schneider Electric Acti9 Vigi iC40 series. This device is designed to enhance electrical safety by detecting residual currents and quickly disconnecting the circuit to prevent electric shock and fire hazards. It features a 1P+N (one pole plus neutral) configuration, making it suitable for single-phase electrical systems. The device has a rated current of 40 A, indicating the maximum current it can handle continuously. It is sensitive to AC type residual currents, with a tripping sensitivity of 300 mA. This level of sensitivity provides a balance between protection and minimizing nuisance tripping. The Acti9 Vigi iC40 series is known for its robust design and reliable performance in demanding electrical environments. It is commonly used in residential, commercial, and industrial applications to provide enhanced protection against electrical faults. The A9Y83640 add-on RCD seamlessly integrates with compatible circuit breakers, offering a compact and efficient solution for upgrading existing electrical panels. Its primary function is to monitor the current balance in a circuit and trip when an imbalance, indicative of a leakage current, is detected.
