ABB 1SDA070448R1 Switch Disconnector - 4P 1000V DC UL
Part Number: 1SDA070448R1
Quick Summary
ABB 1SDA070448R1 Switch Disconnector isolates high‑voltage DC power in industrial systems for safe maintenance and reliable startup. Too often, maintenance teams face arc-flash risk and downtime when isolation relies on manual methods. This model carries UL/CSA listings, a CE declaration of conformity, and supports 1000 V DC insulation with 8 kV impulse withstand, helping facilities meet global safety and regulatory requirements. With stored energy operation and a four-pole design, installation is straightforward and predictable. From a procurement perspective, the combination of reliability, install‑friendly front terminals, and documented compliance reduces risk and total cost of ownership across DC protection schemes.

FAQs
Ensure the panel cutout accommodates the device footprint (280 mm width, 268 mm height, 178 mm depth) and mount per manufacturer guidelines. Connect front terminals to the DC feeders with proper torque and shielding, verify insulation integrity, and ensure the stored-energy mechanism is securely loaded before powering. Check that the assembly aligns with Tmax T system requirements and that protective covers are in place for maintenance access.
Key specs include four poles, DC operation, 1000 A rated current, 1000 V DC rated insulation and nominal voltage, 8 kV rated impulse withstand, and 18 kA short-time withstand current for 1 s. These ratings support high‑demand DC protection with robust fault isolation, while ensuring compliance with UL standards and CE declarations for global deployments.
Yes. The four‑pole design with stored-energy operation is well-suited for data centers, manufacturing lines, and solar/storage DC feeders. Its front-terminal configuration simplifies panel integration, while UL/CSA listings and CE conformity help meet regulatory requirements across regions. The device also supports high current and high fault‑level protection essential in critical DC networks.
The 1SDA070448R1 carries UL and CSA listings and a CE Declaration of Conformity. It complies with RoHS guidelines and aligns with Tmax T documentation for special applications. These certifications streamline procurement, reduce compliance risk, and support cross‑border deployment in regulated facilities.
The stored-energy mechanism enables rapid, reliable re‑energization after fault events, lowering downtime and maintenance effort. Front terminals simplify wiring and inspections, while documented compliance reduces audit overhead. Over the product’s life, this translates to lower total cost of ownership, fewer spare parts, and improved system availability in DC protection schemes.
