A9DE7720 SCHNEIDER ELECTRIC

The A9DE7720 is a Residual Current Breaker with Overcurrent protection (RCBO) from Schneider Electric's Acti9 iCV40N series. This RCBO is designed to protect electrical circuits from both overcurrents and residual current faults, enhancing safety and preventing electrical hazards. It features a 3P+N (three poles plus neutral) configuration, making it suitable for three-phase electrical systems with a neutral conductor. The device has a current rating of 20A and a C curve tripping characteristic, which means it is designed to trip relatively quickly for moderate overloads and faster for higher overloads, providing effective protection for a range of applications. With a breaking capacity of 6000A, it can safely interrupt high fault currents, preventing damage to equipment and ensuring the safety of personnel. The RCBO is an AC type, indicating its suitability for alternating current systems. It has a residual current sensitivity of 300mA, which means it will trip when a leakage current of 300mA or greater is detected, preventing electric shock and fire hazards. This RCBO combines the functions of a circuit breaker and a residual current device in a single unit, saving space and simplifying installation. It is ideal for use in commercial, industrial, and residential applications where both overcurrent and residual current protection are required. The Acti9 iCV40N series is known for its reliability, performance, and ease of installation, making it a popular choice among electrical professionals.
