ABB 1SDA123633R1 Moulded Case Circuit Breaker - 8 kV
Part Number: 1SDA123633R1
Quick Summary
1SDA123633R1 is a DC Moulded Case Circuit Breaker designed for reliable protection in 750 V DC power distributions. This ABB device helps protect critical DC buses in industrial control, data centers, and automated facilities by rapidly interrupting fault currents while minimizing downtime. Engineers face uptime and safety challenges in high-energy DC networks, making a robust MCCB essential. With IEC 60947-2 conformity and CE declarations, plus RoHS and REACH compliance, the XT6 family aligns with ABB EcoSolutions for greener end-of-life outcomes. The combination of a 630 A nominal rating and 800 A uninterrupted service delivers operational resilience, while 8 kV impulse withstand supports harsh electrical environments. These features translate into lower total cost of ownership and improved system reliability for your DC protection strategy.

Feature → Business Impact → Application: 630 A rated current and 3P configuration provide strong bus protection for medium- to high-load DC networks, reducing fault impact and enabling quick isolation in industrial power distribution. This supports higher line uptime and safer operation in automation cell banks, machinery, and DC distribution panels. Feature → Business Impact → Application: 800 A uninterrupted current rating ensures continuous protection under heavy DC load conditions, enabling data centers and manufacturing lines to sustain critical processes even during brief overload events. Feature → Business Impact → Application: 750 V DC rated operational voltage with 1000 V insulation voltage expands safe integration in high-energy applications, allowing tighter enclosure design and improved clearance margins in compact switchgear. Feature → Business Impact → Application: 8 kV rated impulse withstand voltage (Uimp) plus IEC 60947-2 compliance provides robust protection against transient surges, supporting telecom and industry 4.0 power rails with reduced risk of nuisance trips. Feature → Business Impact → Application: Fixed circuit-breaker terminal connection simplifies installation and service in standard enclosures, enabling faster commissioning and easier retrofits in control cabinets and MCCs. Feature → Business Impact → Application: 34.4 W per pole power loss under rated conditions improves energy efficiency in continuous-duty DC systems, lowering heat load and cooling requirements in high-density switchgear. Feature → Business Impact → Application: 20000 mechanical cycles and a 3P XT6 sub-type deliver reliable long-term operation in demanding environments, reducing maintenance frequency and extending service life across production lines. Feature → Business Impact → Application: Environmentally aware packaging, 60% recyclability target per EN45555, and EPD/REACH/RoHS declarations simplify compliance and enable greener lifecycle management for ABB EcoSolutions projects. This combination of protection, efficiency, and sustainability is particularly suited for data centers, electric traction, and industrial automation where reliability and regulatory alignment are non-negotiable.
