ABB 1SDA116351R1 Moulded Case Circuit Breaker - IEC

Feature → Business Impact → Application: The 4P configuration and 125 A nominal rating provide precise current protection and coordination in multi-branch power distributions, reducing nuisance trips and equipment damage in automated manufacturing lines. This translates to improved line uptime and safer startup sequences for robotics cells and conveyors embedded in control panels. The 87.5–125 A setting range enables tight IT/OT coordination and selective tripping when downstream faults occur, streamlining maintenance and reducing write-downs on spare parts. Release via TMD with TM characteristics enhances fast, predictable protection against short-circuit events, lowering the likelihood of cascading faults in high-density panels. Front-terminal connections simplify wiring and enable faster commissioning, especially in retrofit projects where enclosure depth is constrained. The 500 V AC / 250 V DC rated operating voltage, coupled with a 6.60 W power loss figure, supports energy-efficient operation in continuous-process applications. Mechanical durability of 20,000 cycles ensures long service life in demanding industrial environments, while RoHS, REACH, CMRT, and TSCA declarations reduce compliance risk across global installations. Compatible with P2 power distribution schemes and SACE FORMULA DSP architectures, it integrates seamlessly with modern automation architectures and PLC interfaces, delivering consistent protection without compromising panel real estate.
