Feature → Business Impact → Application: The 3P DC MCCB design (200 A, 750 V DC) provides high fault current protection to critical DC distributions, reducing downtime and equipment damage in automation panels. This translates to increased line uptime and safer control circuits in manufacturing lines and battery storage systems. The fixed terminal connection speeds up installation, lowers wiring errors, and supports reliable field maintenance in control cabinets and enclosure-based DC ro systems. Power loss is rated at 11.88 W per pole, offering predictable thermal performance and easier cooling planning in harsh plant environments, contributing to energy efficiency and lower operating costs. With IEC 60947-2 and GB/T 14028.2 compliance, plus a CE declaration, your compliance burden is reduced while remaining aligned with global standards and customer audits. End-of-life disassembly instructions and a recyclability rate of 56.3% (EN45555) improve sustainability reporting and supplier footprint. The product’s release (TMA) and TM Type (XT4) support robust nuisance fault handling in demanding operations, while fixed-terminal installation minimizes field modification and accelerates commissioning. Industry-specific context shows MCCBs like this are essential in DC power distribution for automation panels, rail traction interfaces, and industrial motor drives, where uptime and safety are non-negotiable. In short, this ABB MCCB supports reliability, safety, and sustainability objectives in modern industrial automation projects while remaining compatible with XT4 and standard enclosure practices.

FAQs
Yes. The 1SDA123593R1 is designed for the XT4 family with fixed-terminal connections, enabling straightforward retrofit or new-panel installations. Its dimensions (105 mm width, 160 mm height, 82.5 mm depth) fit standard MCCB apertures, reducing panel rework and ensuring reliable field wiring. This compatibility minimizes commissioning time and wiring errors in control cabinets.
Ics (rated service short-circuit breaking capacity) and Icu (ultimate short-circuit rating) indicate the maximum fault current the breaker can interrupt in service or under fault conditions. For this device, Ics/Icu are 85 kA across voltages from 250 V DC to 750 V DC, ensuring robust protection for mid- to high-current DC systems like automation panels and battery storage, while meeting IEC 60947-2 requirements.
This ABB MCCB is ideal for DC distribution in control cabinets, automation panels, and battery energy storage systems. Its 3P design suits three-phase DC circuits, while the 200 A rating supports mid-to-large control and automation loads. It is particularly valuable in facilities prioritizing uptime, safety, and compact panel layouts, with straightforward installation in new builds or retrofits.
The device aligns with IEC 60947-2 and GB/T 14028.2 standards, and carries a CE Declaration of Conformity. It is RoHS compliant, with REACH declarations, and provides end-of-life guidance, including disassembly instructions. These certifications help customers meet regulatory requirements and pass audits in global manufacturing and automation environments.
With a mechanical durability of approximately 25,000 cycles and a consistent 11.88 W power loss per pole, the MCCB supports predictable thermal management and reduced cooling costs. Its fixed-terminal installation and standardized dimensions simplify maintenance, inventory, and spare parts management. The combination of high Ics/Icu ratings, CE/IEC compliance, and lifecycle guidance enables lower total cost of ownership for DC protection in automation projects.
