It typically trips at 8–12× rated current (here, 160–240 A magnetic release). This makes it suited for circuits with moderate inrush — motor starters, transformer primaries, or inductive loads where a B curve would nuisance-trip but a D curve would be too slow. For a 20 A K-curve breaker, the thermal element handles overloads (1.13–1.45× In per IEC 60898), while the magnetic element clears short-circuits fast enough to protect downstream wiring.","metaTitle":"ABB S801S-K20 MCB S800S 1P K 20A, 50 kA","metaDescription":"ABB S801S-K20 S800S series MCB, 1-pole, Trip Curve K, 20 A, 230 VAC, 50 kA interrupting rating.
