A9Y82640 SCHNEIDER ELECTRIC

The A9Y82640 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 1P+N (one pole plus neutral) configuration, making it suitable for single-phase electrical systems. It has a rated current of 40 A, indicating its capacity to handle circuits with a maximum current demand of 40 amperes. The A9Y82640 offers a sensitivity of 30 mA, meaning it will trip and interrupt the circuit when a leakage current of 30 milliamperes or greater is detected, minimizing the risk of electric shock. This RCD is specifically designed to detect AC type residual currents, which are sinusoidal alternating currents. It provides reliable protection against indirect contact hazards and reduces the risk of fire caused by persistent earth fault currents. The Acti9 Vigi iC40 series is known for its robust construction and compliance with international standards, ensuring long-term performance and safety. This add-on RCD seamlessly integrates with iC40 miniature circuit breakers (MCBs), creating a compact and efficient solution for residual current protection. By adding the A9Y82640 to an existing iC40 MCB, users can easily upgrade their electrical panel to meet modern safety requirements.
