A9Y64640 SCHNEIDER ELECTRIC

The Acti9 iDT40 A9Y64640 is a Vigi add-on residual current device (RCD) module designed for integration with iDT40 miniature circuit breakers (MCBs). This module provides enhanced protection against electrical hazards, specifically earth leakage faults. It is configured for a 1P+N (one pole plus neutral) electrical system, making it suitable for single-phase applications. The A9Y64640 has a rated current of 40A, indicating the maximum current it can handle continuously. It features a sensitivity of 30mA, meaning it will trip when a leakage current of 30mA or greater is detected, offering a high level of protection against electric shock. The RCD is of Type A SI (Super Immunized), providing increased immunity to nuisance tripping caused by transient overvoltages or harmonic currents. This ensures reliable operation in environments with electrical disturbances. The Acti9 series is known for its quality, reliability, and safety features, making it a trusted choice for electrical protection in residential, commercial, and industrial applications. This module enhances safety by quickly disconnecting the circuit in the event of a ground fault, preventing potential harm to people and equipment.
