ABB 1SDA062868R1 Moulded Case Circuit Breaker - PR331/P LSIG

High current capability with 1250 A rating enables reliable protection for large motor feeders and transformer circuits, reducing the risk of cascading faults and unplanned downtime while enabling scalable distribution to meet growing demands. Business impact includes improved uptime and safer distribution, with the application suitable for heavy-load panels in manufacturing and process facilities. The 3P fixed front-terminal design simplifies installation and service, delivering faster assembly and easier wiring checks in tight electrical rooms, reducing commissioning time and field errors in industrial environments. The PR331/P LSIG release provides precise, time-coordinated tripping, supporting selective coordination and reduced downstream damage in fault events. With a rated operational voltage of 690 V AC and Ui of 1000 V, the device supports robust protection across common industrial feeders, while the Icu/Ics values (up to 85 kA/50 kA) enable resilience against high fault currents. RoHS, REACH, and SCIP compliance streamline procurement for regulated industries, and the product’s footprint and weight (9.7 kg) support straightforward cabinet integration and panel upgrades. The device’s electrical durability of 2000 cycles and mechanical durability of 10000 cycles translate to predictable maintenance needs and lower lifecycle costs, while the packaging and data documentation simplify spare parts planning and compliance reporting. Typical applications include power distribution to transformers, motor control centers, and large machine feeds in petrochemical, metal fabrication, and packaging facilities, where fast, reliable disconnection is essential to preserve equipment and personnel safety. Compatibility with ABB SACE Tmax T7 lines ensures seamless integration into existing protection schemes and enables customers to leverage familiar engineering workflows and Spare Parts ecosystems.
