ABB 1SDA123608R1 MCCB - 4P XT5 DC 630A IEC 60947-2

Feature → Business Impact → Application: 630 A rated current enables handling large DC loads without nuisance tripping, reducing downtime and improving line continuity in data centers, manufacturing lines, and DC distribution cabinets. In practice, this means fewer interruptions during peak demand and more predictable performance for critical loads. Feature → 4P configuration provides four independent poles in a compact footprint, streamlining space planning and enabling coordinated protection across multiple DC feeders in switchgear. Application: motor control centers and drive systems requiring centralized, reliable protection with simplified wiring. Feature → 750 V DC rated operational voltage and 1000 V DC insulation support safe operation across high-energy DC networks, ensuring proper isolation during faults. Application: renewable energy interfaces, industrial DC buses, and traction-related equipment. Feature → 8 kV rated impulse withstand voltage and 36 kA short-circuit capacity deliver robust protection against transients and high-energy faults. Business impact: enhanced system resilience and reduced risk of cascading failures in critical lines. Application: bulk DC distribution, battery storage systems, and substations. Feature → TM release (TMA) and XT5 family compatibility provide precise tripping characteristics for DC fault conditions while maintaining compatibility with ABB’s XT5 ecosystem. Application: retrofit upgrades and new installs in automation cells where standardization matters. Feature → 4P fixed terminal connection simplifies installation and cabling, enabling faster assembly and more reliable torque retention in harsh environments. Application: panel-building and greenfield projects with tight schedules. Feature → Environmental and material compliances (RoHS, REACH, EPD) support sustainable design and regulatory adherence. Business impact: easier supplier audits and lower lifecycle risk. Application: industries with strict environmental and product stewardship requirements. Feature → Mechanical durability of 20,000 cycles and 47.8 W power loss per pole supports long service intervals and predictable thermal performance. Application: continuous operation environments where reliability and energy efficiency matter. Feature → Width 186 mm, height 205 mm, depth 103 mm with a weight of 4.15 kg offers a compact yet robust footprint for dense switchgear layouts. Application: panel builders seeking space-efficient protection modules without compromising ratings.
