A9Q11340 SCHNEIDER ELECTRIC

The A9Q11340 is an add-on residual current device (RCD) from the Schneider Electric Acti9 Vigi iC60 series, designed to enhance electrical safety in various applications. This device is specifically configured for three-phase (3P) systems, providing comprehensive protection against residual currents. With a rated current of 40A, it is suitable for circuits with moderate to high current demands. The A9Q11340 is classified as AC type, meaning it is designed to detect and respond to sinusoidal alternating residual currents. It features an instantaneous tripping characteristic, ensuring rapid disconnection of the circuit upon detection of a fault current. The sensitivity of this RCD is 30mA, offering a high level of protection against electric shock. It operates within a voltage range of 400 to 415VAC, making it compatible with standard three-phase power systems. This add-on RCD seamlessly integrates with iC60 miniature circuit breakers (MCBs), providing a compact and efficient solution for residual current protection. By detecting and interrupting fault currents, the A9Q11340 minimizes the risk of electrical hazards, protecting both equipment and personnel.
