A9Y70640 SCHNEIDER ELECTRIC

The A9Y70640 is an add-on residual current device (RCD) from Schneider Electric's Acti9 Vigi iCG40 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 substantial electrical loads. The A9Y70640 features a sensitivity of 30 mA, which means it will trip and interrupt the circuit when a leakage current of 30 milliamperes or greater is detected, preventing electrical shocks and reducing the risk of fire. Being an A-type RCD, it is capable of detecting both AC and pulsating DC residual currents, offering broader protection compared to AC-type RCDs. This add-on device works in conjunction with a miniature circuit breaker (MCB) to provide comprehensive protection against overloads, short circuits, and residual currents. Its compact design allows for easy installation and integration into existing electrical panels. The Acti9 series is known for its reliability and robust performance, ensuring long-lasting protection for electrical installations.
