A9Y84725 SCHNEIDER ELECTRIC

The A9Y84725 is an add-on residual current device (RCD) from the Schneider Electric Acti9 Vigi iC40 series, designed to enhance electrical safety in residential and commercial applications. This device is a 3P+N (three-pole plus neutral) configuration, making it suitable for three-phase electrical systems. It has a rated current of 25A, indicating the maximum current it can handle continuously without tripping. The RCD features a sensitivity of 30mA, which is the threshold at which it will detect a leakage current and trip to prevent electrical shock. It incorporates A-SI type protection, offering enhanced immunity to nuisance tripping caused by transient overvoltages or high-frequency currents. This ensures reliable operation even in environments with electrical noise. The Acti9 Vigi iC40 series is known for its robust design and compliance with international standards, providing a high level of protection and peace of mind. This add-on RCD works in conjunction with a miniature circuit breaker (MCB) to provide comprehensive protection against both overcurrent and residual current faults. Its compact design allows for easy installation in standard distribution boards, saving space and installation time. By detecting and interrupting leakage currents, the A9Y84725 significantly reduces the risk of electrical accidents and equipment damage.
