FAQs
When installing the 1SDA081044R1, ensure compatibility with fixed-front terminal arrangements and confirm clearances for 140 mm width and 205 mm height. Use proper lugs and torque settings to maintain IEC-rated electrical durability. Verify the 3P arrangement aligns with the switchgear busbar layout and ensure panel space accommodates the 103.5 mm depth for safe maintenance.
Key ratings include 320 A rated current, 690 V AC nominal voltage, 8 kV rated impulse withstand, and up to 85 kA Ics depending on voltage. These specs support robust short-time and ultimate short-circuit protection, enabling selective tripping in multi-branch circuits and reducing collateral damage during faults in industrial power systems.
Yes. The 1SDA081044R1 is designed for Tmax T5 configurations, offering E-LSIG solid-state release, 3P front-terminal accessibility, and compatibility with 690 V AC systems. Its 320 A rating and 85 kA Ics performance enhance reliability in transformer and feeder protection within Tmax T5 installations.
The device carries CE conformity with EC declarations, RoHS compliance, REACH declarations, CMRT for conflict minerals, and TSCA-related declarations. These certifications support regulatory compliance, safer sourcing, and easier import across global manufacturing sites.
Upgrading to the 1SDA081044R1 can reduce unplanned downtime through faster, selective tripping and improved maintenance access due to front-terminal design. With 3P protection, 320 A capacity, and robust Ics values, facilities often see lower maintenance costs, fewer switchgear outages, and smoother regulatory reporting over the equipment lifecycle.
