Schneider Electric A9N18372 Acti9 Circuit Breaker

Schneider Electric Acti9 circuit breaker, model A9N18372, is an 80 A unit rated for 415 V. Identified by the part number A9N18372, this device belongs to the Acti9 family, which provides compact, modular overcurrent protection for electrical distribution networks. The A9N18372 interrupts current when a fault or overload occurs, helping to prevent damage to conductors and connected equipment. Its 415 V rating places it in typical distribution setups that operate at or below this voltage, making it suitable for safeguarding circuits fed from standard industrial or commercial power systems. As a member of the Acti9 line, this model is designed to fit into compatible Schneider Electric enclosures and panels, enabling straightforward integration with related devices and wiring. For proper selection, ensure pairing with the correct pole configuration and verifying compatibility with your panel's bus arrangement and local electrical codes, since exact installation requirements can vary by installation. This specific part number is ready to be matched to a corresponding protective circuit in systems requiring 80 A protection at up to 415 V, aligning with common protective strategies for wiring insulation, fault containment, and safe shutoff in electrical distributions.
