ABB 1SDA112943R1 Accessory - IEC 60947-2

Four-pole design ensures all poles release simultaneously, reducing arc duration and improving fault clearance. This promotes safer disconnection and better coordination in power distribution and motor feeder panels, especially where XT5 assemblies are used. The business impact is clear: faster fault isolation translates to less downtime and reduced risk for personnel during maintenance. The application is ideal for Tmax XT installations requiring reliable, synchronized release across four poles, with compatibility for XT5 configurations. The AC/DC release type provides versatility across drive and control circuits, enabling the same accessory to support mixed loads and simplifying spare parts inventories, which lowers total cost of ownership. In applications with varying supply conditions, this feature minimizes control mismatches and supports consistent operation. The rated current of 500 A (In) at 50°C ensures robust performance during motor starts and in-rush conditions, reducing nuisance releases and protecting equipment. Four-pole, fully rated release supports high-demand panels and clean disconnection sequences in demanding industrial environments. Loose or configurable installation offers flexible mounting, enabling straightforward retrofits in existing cabinets and reducing engineering effort during upgrades. This adaptability translates into faster deployment and scalable automation. Compliance and declarations (IEC 60947-2, RoHS, REACH, CMRT, TSCA) simplify procurement audits and supplier qualification, while EPD and environmental data support sustainability reporting. Packaging and logistics details, including EAN 8056221029964 and 1-piece minimum order, streamline ordering and inventory planning, supporting just-in-time procurement for panel builders and system integrators.
