The Schneider Electric Acti9 iID (A9R54425) is a premium Four Pole (4P) Residual Current Circuit Breaker (RCCB) designed primarily for 3-phase electrical systems to protect installations against fire hazards and equipment damage caused by earth leakage. With a 300mA sensitivity, it is typically used as a main incoming device or in applications where a higher leakage threshold is required to prevent nuisance tripping. As a Type A RCCB, it provides advanced protection by detecting both alternating current (AC) and pulsating direct current (DC) residual currents.Key FeaturesFire & Equipment Protection: The 300mA sensitivity threshold is specifically designed to prevent fires ignited by earth leakage currents and protect complex 3-phase electrical equipment.Type A Safety: Capable of detecting residual alternating currents as well as pulsating direct currents, making it ideal for modern circuits with electronic components (like variable speed drives, IT equipment, and heavy LED lighting loads).3-Phase Application: 4-Pole (4P) design is engineered to protect three-phase installations with a neutral.VisiSafe & VisiTrip Technology: Standard in the Acti9 range, it includes a green indicator for safe downstream maintenance (VisiSafe) and a red window on the front face for clear fault trip indication (VisiTrip).High Immunity: Advanced design prevents nuisance tripping in electrically polluted environments.Seamless Integration: Fully compatible with the broader Acti9 system, easily pairing with standard MCBs for complete circuit and earth fault protection.Technical SpecificationsFeatureSpecificationBrandSchneider ElectricSeriesActi9 iIDModel NumberA9R54425Current Rating25APolesFour Pole (4P / 3P+N)Earth-Leakage Sensitivity300mAProtection ClassType A (AC & pulsating DC)Operating Voltage (Ue)380...415V AC (50/60 Hz)Weight~370 gSEO KeywordsSchneider Acti9 iID A9R54425, 25A 300mA RCCB, Type A RCCB, Schneider 4P RCCB, 3-Phase Earth Leakage Circuit Breaker, Fire Protection RCCB, Acti9 RCCB Bangladesh, A9R54425 Price BD.Note: A 300mA RCCB is generally intended for fire and equipment protection, not for direct personnel life protection (which requires 30mA).
