ABB 1SDA123535R1 Moulded Case CB - DC 50A 4P IEC 60947-2

Feature → Business Impact → Application: The 50 A DC rating and 4P configuration deliver reliable overload and short-circuit protection for DC power rails in automation panels, reducing unplanned downtime and equipment damage in motor drives and battery-backed systems. This enables predictable maintenance cycles and enhanced uptime in critical manufacturing lines. Feature → Business Impact → Application: Rated insulation of 1000 V and impulse withstand of 8 kV improves resilience against surges and transients common in renewable and DC bus configurations, supporting safer startup sequences and improved system integrity in high-energy environments. Feature → Business Impact → Application: Fixed circuit-breaker terminals with a compact footprint (120 × 130 × 82.5 mm) simplify panel layout, streamline installation, and save enclosure space in control cabinets and compact MCCs. Feature → Business Impact → Application: ABB EcoSolutions and a recyclability rate of 55.7% per EN45555 help meet corporate sustainability targets and simplify downstream waste management in multi-site projects, supporting green procurement programs. Feature → Business Impact → Application: 25,000 mechanical cycles and 160 A uninterrupted current (Iu) offer long service life and high availability in continuous process control, reducing replacement costs and improving ROI for critical DC distribution. Feature → Business Impact → Application: RoHS/REACH compliance, disassembly guidance, and CE declarations simplify regulatory audits and supplier qualification in regulated sectors such as energy, process automation, and heavy industry.
