A9TDFD620 SCHNEIDER ELECTRIC

The A9TDFD620 from Schneider Electric is an active arc fault detection RCBO (Residual Current Breaker with Overcurrent protection) designed to enhance electrical safety. As part of the Acti9 iCV40H ARC series, this device offers advanced protection against arc faults, reducing the risk of electrical fires. It features a 1P+N (one pole plus neutral) configuration, making it suitable for single-phase electrical systems. With a current rating of 20A and a C curve tripping characteristic, it provides reliable overcurrent protection for various applications. The device incorporates a 30mA residual current sensitivity, offering protection against earth leakage faults. It is a type A-SI RCBO, indicating its ability to handle alternating current and pulsating DC residual currents with enhanced immunity to nuisance tripping. The A9TDFD620 has a breaking capacity of 10000A, ensuring it can safely interrupt high fault currents. This combination of arc fault, overcurrent, and residual current protection makes it a comprehensive solution for electrical safety. It is ideal for use in residential, commercial, and industrial settings where enhanced electrical fire protection is required.
