ABB 1SDA123579R1 Moulded Case Circuit Breaker - IEC 60947-2

Feature → Business Impact → Application: The 50 A, 4P configuration delivers robust DC protection with a 500 V DC operating rating, translating to reliable safeguarding of power rails and drives while keeping energy losses at a measured 4.09 W per pole. Application is in DC distribution for automation panels and renewable energy interfaces, where predictable protection lowers downtime and maintenance costs. Feature → Business Impact → Application: A high short-circuit capacity of (250 V DC) 100 kA and (500 V DC) 50 kA (2 or 3 poles in series, respectively) ensures swift interruption of faults, reducing arc exposure and equipment damage in heavy fault conditions. Application spans data centers, motor drives, and inverter interfaces requiring fast, dependable fault handling. Feature → Business Impact → Application: With 25,000 mechanical cycles and fixed terminal connections, the device supports frequent switching without premature wear, extending service life and lowering lifecycle costs in automated lines and panel assemblies. Application includes CNC machinery and packaging lines with regular on/off cycles. Feature → Business Impact → Application: Low power loss per pole combined with compact dimensions (120 mm x 130 mm x 82.5 mm) improves panel density and cooling efficiency, enabling smaller enclosures and lower installation costs in automation cabinets. Application: small footprint DC distribution points and retrofits in retrofitting projects. Feature → Business Impact → Application: Sustainability and compliance features (EPD, RoHS, REACH, EN45555 recyclability 55.7%, and disassembly guidance) simplify regulatory reporting and green procurement programs, supporting corporate ESG goals in industrial plants and energy facilities.
