A9N19450 SCHNEIDER ELECTRIC

The A9N19450 from Schneider Electric is a Librio Vigi C40 earth leakage add-on block, designed to enhance the safety of electrical installations. This device is specifically configured for 1P + N (1 Pole + Neutral) systems, providing comprehensive protection against earth leakage faults. With a sensitivity of 30 mA, it promptly detects even small leakage currents, minimizing the risk of electric shock and fire hazards. The Vigi C40 add-on block seamlessly integrates with compatible circuit breakers, offering a compact and efficient solution for residual current protection. Its primary function is to continuously monitor the current balance within the circuit, and upon detecting an imbalance exceeding 30mA, it instantly trips the associated circuit breaker, disconnecting the power supply. This rapid response is crucial in preventing severe electrical accidents and equipment damage. The A9N19450 is suitable for a wide range of applications, including residential, commercial, and industrial settings, where reliable earth leakage protection is essential. Its robust design and compliance with international standards ensure long-term performance and safety. By adding this earth leakage protection, electrical systems are safer and more reliable.
