A9N19499 SCHNEIDER ELECTRIC

The A9N19499 from Schneider Electric's Librio series is a Vigi C40 earth leakage add-on block, designed to enhance electrical safety in residential and commercial applications. This device is specifically configured for 1P + N (1 Pole + Neutral) electrical systems, providing comprehensive protection against earth leakage faults. It features a sensitivity setting of 300 mA, which is suitable for applications where a higher level of leakage current is tolerable, such as circuits feeding lighting or heating. The Vigi C40 add-on block works in conjunction with a compatible circuit breaker to quickly detect and interrupt the circuit when an earth leakage fault is detected, minimizing the risk of electrical shock and fire. Its modular design allows for easy installation and integration with existing electrical panels. By continuously monitoring the current balance, the A9N19499 ensures ongoing protection against potentially dangerous earth leakage currents. This earth leakage add-on block is essential for maintaining a safe electrical environment and preventing electrical accidents. It adheres to international standards for safety and performance, guaranteeing reliability and long-term operation. The A9N19499 is a crucial component for any electrical system prioritizing safety and protection against earth leakage faults.
