FAQs
The 1SDA123630R1 is a fixed circuit-breaker (4P) designed for standard ABB and compatible MCCB panelboard configurations. It fits in panels using fixed circuit-breaker mounting with compatible busbar spacing and standard IEC 60947-2 termination practices. Ensure panel cavity dimensions accommodate 186 mm width, 205 mm height, and 103 mm depth, and confirm a 400 A rating with 750 V DC operating conditions.
Key ratings include Rated Current (In) 400 A, Rated Insulation Voltage (Ui) 1000 V, Rated Operational Voltage (Ue) 750 V DC, and Short-Circuit Breaking Capacity (Ics/Icu) up to 100 kA depending on voltage level. It also features a 4P configuration, DC current type, and a release set for Tmax XT5 TM, meeting IEC 60947-2 requirements.
Yes. With DC operation, 4P construction, and high Ics/Icu ratings, 1SDA123630R1 is suitable for DC bus protection in motor-drive systems and other high-energy DC power architectures. Its 750 V DC operating voltage and 400 A rating support reliable decoupling of drives and safe shutdowns during fault conditions, reducing device damage and downtime.
The device complies with IEC 60947-2 and GB/T 14028.2, and ships with a CE Declaration of Conformity. It also has RoHS and REACH declarations, plus ABB EcoSolutions documentation for end-of-life and recyclability, supporting regulatory and sustainability requirements across multinational projects.
ABB EcoSolutions provides disassembly instructions for end-of-life handling, packaging disposal guidance, and environmental data like EPD. The product’s mechanical durability of up to 20,000 cycles and low per-pole power loss (24.1 W) translate to lower maintenance costs and longer service intervals, boosting total cost of ownership in high-demand industrial environments.
