ABB 1SDA116347R1 Moulded Case Breaker - SACE DSP

The 3P moulded case breaker design protects three-phase loads in common switchgear cabinets, enabling coordinated shutoff across all lines and preventing exposed-arcing during faults. This configuration reduces fault cascades, speeds up recovery, and is ideal for P2 power distribution in control panels and industrial automation racks. The 125 A rated current with an adjustable setting range of 87.5–125 A and an instantaneous I_i of 1250 A provides precise protection, improving motor protection coordination and minimizing nuisance trips in high-load lines. Front terminal connections simplify wiring, accelerate installation, and ease future maintenance or retrofits in existing equipment. Rated voltage of 500 V AC / 250 V DC with Ui of 750 V supports mixed-voltage automation architectures, enhancing universal applicability across plant networks. High short-circuit performance (I_cs up to 50 kA at 240 V AC and 36 kA at higher voltages) combined with I_cu up to 50 kA ensures robust fault handling. The device’s mechanical durability of up to 20000 cycles and a compact footprint reduce replacement intervals and maintenance costs. A measured power loss of 6.60 W minimizes heat load, lowering cooling requirements in enclosed cabinets. Compliance with RoHS, REACH, CMRT, and TSCA, plus WEEE considerations, simplifies cross-border sourcing and regulatory reporting. This MCCB is well-suited for P2 distribution in automation cells, machine lines, and multi-vendor control panels, delivering reliable protection with predictable lifecycle costs.
