A9Y81725 SCHNEIDER ELECTRIC

The A9Y81725 is an add-on residual current device (RCD) from the Schneider Electric Acti9 Vigi iC40 series, designed to enhance electrical safety in various applications. This device is a 3P+N (three-pole plus neutral) configuration, making it suitable for three-phase electrical systems with a neutral conductor. It has a rated current of 25A, indicating the maximum current it can handle continuously without tripping. The RCD features a sensitivity of 300mA, meaning it will trip when a leakage current of 300mA or greater is detected, providing protection against earth faults and electric shock. It is classified as Type A, signifying its ability to detect both AC and pulsating DC residual currents. This add-on RCD works in conjunction with a miniature circuit breaker (MCB) to provide comprehensive protection against overloads, short circuits, and residual currents. The Acti9 Vigi iC40 series is known for its reliability, durability, and ease of installation, making it a popular choice for residential, commercial, and industrial electrical installations. By adding this RCD to an existing MCB, users can significantly improve the safety of their electrical systems and protect against potential hazards. It helps ensure compliance with safety standards and regulations.
