A9N18595 SCHNEIDER ELECTRIC

The A9N18595 is a Vigi C120 earth leakage add-on block from Schneider Electric, designed to enhance circuit protection. This device is specifically configured for use with 3-pole circuit breakers, providing an additional layer of safety against earth leakage faults. It features a sensitivity setting of 300mA, which means it will trip the connected circuit breaker when an earth leakage current of 300mA or greater is detected. The A9N18595 is classified as a Class A device, indicating its suitability for detecting AC residual currents. This add-on block works by continuously monitoring the balance of current flowing through the conductors. If an imbalance occurs, indicating a leakage to earth, the Vigi C120 instantly trips the associated circuit breaker, preventing electrical shock and minimizing the risk of fire. Its robust design ensures reliable performance in various environmental conditions. It is easy to install and integrates seamlessly with compatible C120 circuit breakers, making it an ideal solution for both new installations and retrofits. By adding earth leakage protection, the A9N18595 significantly improves the overall safety and reliability of electrical systems.
