FAQs
To install the ABB 1SDA123551R1, mount the unit in a suitable enclosure rated for DC operation and ensure front-terminal access for wiring. Use the fixed-terminal configuration to minimize connector movement, tighten terminals to the recommended torque, and align the device with the 3P arrangement for stable operation. This setup simplifies wiring, reduces panel depth, and speeds up commissioning in automation panels.
Key specs include a rated current of 160 A, a rated insulation voltage of 1000 V, and a rated operational voltage of 500 V DC. The unit provides short-circuit protection with a service level of 85 kA in series for 2-pole configurations and 3-pole configurations, a rated impulse withstand of 8 kV, and a power loss of about 16.15 W per pole under rated conditions.
Yes. The 3P DC MCCB design, XT2 release, and 160 A rating are well-suited for DC distribution in data centers and automation panels. Its front-terminal wiring enables compact panel layouts, while the high Ics/Icu ratings and 500 V DC capability ensure reliable protection against short circuits, aiding uptime in critical facilities.
The device references IEC 60947-2 as its primary standard, with CE conformity and related DoC, RoHS and REACH declarations, and environmental data like EPD for Tmax XT2/XT2 TM. These certifications support regulatory compliance across regions, enable green procurement, and provide traceable material and disposal guidance for end-of-life planning.
Expect improved uptime from robust thermal and electrical design, with 3P DC protection aligned to IEC 60947-2. Maintenance benefits include predictable replacement cycles due to defined mechanical durability and reliable trip performance. The upfront investment is offset over time by reduced fault-related downtime, easier panel integration, and lower lifecycle waste impact thanks to EcoSolutions alignment.
