ABB 1SDA066505R1 Moulded Case Circuit Breaker - TMF Release

Feature TMF release provides precise thermal-magnetic protection, delivering fast, reliable tripping to minimize fault damage and downtime. Business Impact improved safety margins and shorter outage duration, enabling quicker restoration of critical processes in control panels. Application ideal for main-circuit protection in industrial panels, transformers, and gensets, where predictable coordination reduces cascading trips. Feature Front-terminal connection simplifies wiring, speeds field installation, and reduces wiring errors in dense switchgear environments. Business Impact faster assembly, safer terminations, and easier retrofits. Application suited for new builds and upgrades in manufacturing lines requiring robust UL/IEC compliance and traceable material declarations. Feature Mechanical durability rated at Nr. Operations 8500 cycles and Electrical durability at 1500 cycles, extending service life in high-usage applications. Business Impact lower maintenance costs and longer replacement intervals, improving total cost of ownership. Application aligns with modern assembly practices and scheduled maintenance programs. Feature Rated Current Main Circuit of 90 A, Rated Uninterrupted Current of 125 A, and Ui of 690 V, enabling compatibility with typical industrial feeders. Business Impact supports scalable protection in medium-power distribution, reducing the need for frequent component changes. Application suitable for panels with 550 V AC / 250 V DC operating voltages. Feature Short-Circuit Capacities Ics and Icu across multiple voltages (e.g., 25 kA at 240 V AC, 18 kA at 380 V AC, down to 2.5 kA at 500 V AC / 10 kA DC), ensuring strong fault-handling performance. Business Impact mitigates risk in high-energy systems and supports safe, code-compliant operation. Application appropriate for transformer and motor-control environments where rapid, predictable interrupting capability is crucial.
