The Trip Curve K characteristic means it trips between 8 and 12 times rated current on short-circuit — designed for motor and inductive loads where inrush is higher than a resistive load but you still want fast clearing on a hard fault. That SCCR matters when the upstream transformer is big or the available fault current is known to be high — it avoids cascading failure downstream.","metaTitle":"S802S-K80 ABB High Perf MCB, 80A 2P Curve K, 50kA","metaDescription":"S802S-K80 ABB high-performance MCB, 80 A, 2-pole, Trip Curve K, 230 VAC, 50 kA interrupting rating.

The S802S-K80 is 80 A, Curve K, 50 kA. They share the same DIN-rail footprint, but the current rating, trip curve, and interrupting capacity are completely different.
