ABB 1SDA116433R1 Moulded Case Circuit Breaker - 50 kA @ 240V IEC

Three-pole design rated to 320 A at 500 V AC provides robust protection for medium-size motors used in conveyors and machine tools. This enables selective tripping and reduces nuisance outages in year-round operation. The instantaneous trip setting is adjustable from 2240 to 4160 A, allowing precise coordination with motor starters and soft starters to prevent unnecessary trips during startup while preserving safety. In addition, the unit delivers short-circuit protection with I_cs up to 50 kA at 240 V and I_cu up to 20 kA at 500 V, ensuring safe interruption across a range of distribution voltages and minimizing arc fault risks in panel boards. Mechanical durability of 15,000 operation cycles (at 240 cycles/hour) supports high-usage environments, reducing replacement intervals and maintenance costs. Front-terminal connection simplifies installation and wiring in tight control panels, accelerating commissioning and facilitating retrofits. Compatibility with the SACE FORMULA DSP family enables seamless integration into existing motor protection schemes (P3) while maintaining a compact footprint. Compliance highlights include REACH and RoHS declarations, CMRT for conflict minerals, and TSCA declarations, which help meet global procurement and regulatory requirements and improve supplier transparency. By combining robust electrical performance with practical installation advantages and strong environmental compliance, this MCCB helps engineering teams reduce lifecycle costs while enhancing plant reliability.
