ABB 1SDA070471R1 Switch Disconnector - UL 1000V DC

Feature → Business Impact → Application: The 3-pole DC switch disconnector design enables complete isolation of all poles in a single operation, reducing exposure risk during maintenance and improving system reliability in PV and DC distribution applications. This supports safer commissioning and faster fault isolation, minimizing downtime in solar farms and DC power rooms. Feature → high current capability (400 A) and 1 s Icw of 5 kA provides robust fault tolerance, enabling continued operation of adjacent circuits during short-time faults and protecting downstream equipment. This is particularly valuable in 3P DC feeders and battery energy storage or telecom power systems requiring rapid disconnection under fault conditions. Feature → rated insulation and operating voltages (Ui and Ur 1000 V DC) ensure compatibility with common DC networks and PV arrays, simplifying system design and installation. This reduces engineering complexity and procurement risk for new builds or retrofits. Feature → UL-listed and CE-certified with RoHS/REACH declarations gives compliance confidence for global projects, supporting faster approval cycles and easier vendor qualification. This helps procurement teams avoid delays and rework while ensuring environmental and safety standards are met. Feature → Front-terminal access and specified dimensions (140 mm width, 205 mm height, 103.5 mm depth) facilitate straightforward installation and wiring, improving assembly speed and reducing cabinet congestion in compact switchgear. This is especially beneficial for retrofit projects or space-constrained installations. Feature → EPD, CMRT, TSCA, and WEEE information support sustainability reporting and responsible sourcing, aiding in corporate ESG initiatives and customer audits. This aligns with modern procurement mandates without sacrificing performance.
