ABB 1SDA051088R1 T2L 63A 3P F IEC Circuit Breaker, Current L

For a site electrical engineer working on selectivity or coordination studies, the 63A frame and F curve give predictable short-circuit performance within the T2L platform. The T2L family is a compact MCCB line from ABB, widely used in IEC markets. If you're replacing an older ABB SACE or Tmax breaker, check the mounting footprint — the T2L uses a different base plate than the older T1 series.
