High-current readiness and a four-pole architecture deliver efficient protection for large feeders, reducing the risk of busbar overload and voltage sag. This 1250 A In rating supports substantial loads in manufacturing lines and data-center feeders, translating to fewer upstream trips and better process stability. Front-terminal, fixed breaker design simplifies wiring, speeds installation, and minimizes commissioning time in compact switchgear, enabling tighter panel layouts and easier future upgrades. The device offers a high fault-current capability with Ics up to 85 kA and Icu up to 30 kA, delivering robust protection for motors, transformers, and critical loads without overtripping in normal transients. Rated operational voltage of 690 V AC and insulation voltage of 1000 V ensure compatibility with common industrial power systems while maintaining a generous safety margin. Compliance with IEC standards and environmental declarations (RoHS, REACH, TSCA) support regulatory programs and green procurement goals, while SACE Tmax T family compatibility guarantees cohesive protection curves and maintenance pathways. The product’s electrical durability of 2000 cycles and mechanical durability of 10000 cycles reduce maintenance downtime and extend service life, improving total cost of ownership in harsh industrial environments. Front-terminal access and EMC-friendly construction help streamline preventive maintenance and diagnostics in control panels and switchgear cabinets, delivering measurable efficiency gains and safer operation.
