Feature → Business Impact → Application: The 4P fixed-circuit-breaker design with front terminals simplifies retrofits and reduces installation time in confined panels, enabling faster changes during commissioning and maintenance in industrial DC systems. This directly translates to lower field labor costs and minimized panel downtime in data centers, battery storage, and motor control centers. Feature → Business Impact → Application: Rated current of 125 A and rated operational voltage of 500 V DC deliver dependable protection for medium‑sized DC feeders, helping maintain system uptime while meeting safety requirements in harsh environments found in manufacturing floors and renewable energy sites. Feature → Business Impact → Application: 8 kV rated impulse withstand and 160 A uninterrupted current (Iu) provide resilience against transient events and continuous operation, supporting compliance with IEC 60947-2 and reducing nuisance trips in critical DC circuits such as drive trains and DC bus architectures. Feature → Business Impact → Application: 4P TM/TMA release and XT2 sub-type offer reliable protection for multi‑branch DC networks, improving fault isolation speed and minimizing collateral damage in complex power plants. Feature → Business Impact → Application: Low power loss (11.4 W per pole) improves overall efficiency and reduces thermal load in compact enclosures, enabling denser layouts and lower cooling requirements in data centers and telecom rack environments. Feature → Business Impact → Application: Environmental and material compliance (EPD, RoHS, REACH) plus 55.7% recyclability enable sustainable design and easier end-of-life management for OEMs pursuing green procurement targets in industrial automation. Feature → Business Impact → Application: End-of-Life disassembly instructions and site meeting waste targets help contractors meet corporate sustainability goals and regulatory expectations when decommissioning or upgrading MCCBs in large installations.

FAQs
This unit uses fixed circuit-breaker terminals with four poles and front-access terminals, simplifying retrofits and enabling faster replacement in crowded panels. Ensure panel niches accommodate the 120 mm width, 130 mm height, and 82.5 mm depth, and verify space for front-terminal access during commissioning to minimize wiring reroutes and downtime.
Expect a rated current of 125 A and a rated operational voltage of 500 V DC, with a rated impulse withstand of 8 kV and a service short-circuit capacity of up to 36 kA in applicable configurations. The unit offers 160 A uninterrupted current and a power loss of 11.4 W per pole, supporting reliable operation in continuous-duty DC networks.
Yes. It conforms to IEC 60947-2, with CE declarations and RoHS compliance, and features a TM/TMA release suitable for protective control in DC drives and energy systems. The 4P design supports comprehensive protection across multiple DC feeders, while front terminals aid in safe, quick maintenance and testing.
The ABB 1SDA123517R1 is accompanied by an EC Declaration of Conformity (CE), installation instructions (XT2 DC IEC), and RoHS declarations. It also aligns with environmental reporting (EPD Tmax XT2 TM) and end-of-life guidance, helping manufacturers meet global compliance and sustainability targets.
With 25,000 mechanical cycles and front-terminal accessibility, maintenance windows are shorter and fault diagnostics faster. The product’s EcoSolutions alignment and 55.7% recyclability support circular economy goals, while 125 A/500 V DC ratings and high Ics/Impedance performance reduce recalibration and replacement frequency, delivering lower total cost of ownership over the lifecycle.
