ABB 1SDA123497R1 is a compact 3-pole DC Moulded Case Circuit Breaker that protects drives and panels with precise tripping. Feature → Business Impact → Application: DC operation with 16 A rated current and 500 V DC insulation voltage reduces nuisance trips in drive startups, improving line uptime in manufacturing lines and packaging systems. Front-terminal, fixed-connection design accelerates installation and reduces panel depth, lowering assembly time and field wiring costs on machine dashboards. The 8 kV rated impulse withstand and 36 kA short-circuit ratings offer robust protection for DC bus bars, preventing cascading faults in multi-drive arrays. Compatibility with XT2 family simplifies spare parts planning and inventory control for OEMs and panel builders. The low power loss of 1.33 W per pole enhances energy efficiency in protective schemes, supporting green manufacturing goals. With a mechanical durability of up to 25,000 cycles, maintenance cycles are extended and total cost of ownership is reduced for critical control systems.
