A9N19447 SCHNEIDER ELECTRIC

The A9N19447 is a Vigi C40 earth leakage add-on block from Schneider Electric's Librio series, designed to enhance circuit protection. This device is specifically configured for 3P + N (three-pole plus neutral) systems, ensuring comprehensive coverage against earth leakage faults. It features a sensitivity setting of 300 mA, providing a balance between protection and minimizing nuisance tripping. The Vigi C40 add-on block works in conjunction with compatible circuit breakers to detect and respond to earth leakage currents. Upon detection of a fault current exceeding the set threshold, the Vigi C40 triggers the circuit breaker to trip, disconnecting the faulty circuit and preventing potential electrical hazards. This add-on block is essential for applications where earth leakage protection is critical, such as in industrial, commercial, and residential installations. It helps to protect people from electric shock and prevent equipment damage due to earth faults. The A9N19447 is easy to install and integrates seamlessly with existing circuit breaker systems, offering a reliable and cost-effective solution for enhanced electrical safety. Its robust design ensures long-term performance and compliance with relevant safety standards.
