A9N18558 SCHNEIDER ELECTRIC

The A9N18558 from Schneider Electric is a Vigi C120 earth leakage add-on block, designed to enhance the safety and protection of electrical installations. This device is specifically configured for use with 3-pole circuit breakers, providing an additional layer of defense against earth leakage faults. With a sensitivity of 300mA, it promptly detects and responds to leakage currents, minimizing the risk of electrical shock and fire hazards. The A9N18558 adheres to Class A standards, ensuring reliable performance in various electrical environments. Its primary function is to monitor the current flowing through the circuit and detect any imbalance indicative of current leakage to earth. Upon detection of a fault, the add-on block triggers the circuit breaker to trip, interrupting the power supply and preventing further damage or injury. This earth leakage add-on block is easy to install and integrate with existing circuit breaker systems, making it a convenient and cost-effective solution for enhancing electrical safety. It is suitable for a wide range of applications, including residential, commercial, and industrial settings. By providing enhanced protection against earth leakage faults, the A9N18558 contributes to a safer and more reliable electrical system.
