Typical applications include Industrial motor protection, Commercial building electrical panels, HVAC systems with high inrush currents, Transformers and welding machines, Replacement in existing Schneider panels, New installations requiring high breaking capacity. It is compatible with or cross-references Schneider Acti9 auxiliary contacts (iOF, iSD, iOF/SD), Schneider Acti9 shunt trip (iMX), Schneider Acti9 undervoltage release (iMN), Schneider Acti9 padlocking device, Schneider Acti9 busbar system. Within industrial automation and process-control environments, components of this type are relied upon to keep critical equipment operating safely and efficiently. They are typically specified where uptime, repeatability and a predictable maintenance cycle matter more than upfront cost. A circuit breaker such as this one forms part of a larger machine or system, so correct identification and fitment directly affect the performance and safety of the whole installation. Schneider parts are widely used across power generation, manufacturing, oil and gas, water and process industries, where engineering teams standardise on proven series to simplify spares planning. When selecting a replacement, confirm the exact model designation and verify that the mechanical and electrical interface matches the unit currently installed. Cross-checking the order code, mounting style and connection type against the existing device helps avoid compatibility issues and unplanned downtime during a maintenance window. Where several variants exist, the suffix often defines voltage, range or firmware, so it should be matched precisely rather than approximated.
