ABB 1SDA116278R1 Moulded Case Circuit Breaker - IEC

Feature → Business Impact → Application: The 1SDA116278R1 offers a setting range of 22.4–32 A and a rated current of 32 A, enabling tailored protection for motor loads and distribution feeders, reducing nuisance trips and extending equipment life in P1 power networks. In practice, this means fewer production interruptions and improved process uptime for manufacturing lines that rely on balanced three-phase protection. The front-terminal connection simplifies wiring and streamlines installation in crowded switchboards, cutting assembly time and minimizing field wiring errors in new builds or retrofits. The device’s high short-circuit ratings (Ics up to 80 kA at 240 V AC; Icu up to 8 kA at 500 V AC) provide a robust safety margin for high-inrush equipment and motor starters, supporting reliable startup sequences and reduced downtime. With a 750 V insulation rating and 500 V AC / 250 V DC operational voltage, it delivers broad compatibility across common industrial applications, including machine control cabinets, drives, and panel distribution. Reliability is reinforced by a mechanical durability rating of 20,000 cycles, delivering long service life in demanding environments and lowering maintenance costs. The product adheres to IEC standards and carries RoHS/REACH declarations, which helps ensure regulatory compliance across global markets and simplifies supplier audits. In practice, this translates to lower total cost of ownership, easier compliance reporting, and greater confidence during expansion projects that require consistent protection across multiple lines.
