It defines the magnetic trip threshold between 8 and 12 times the rated current (80–120 A for this 10 A unit). That is higher than a C-curve (5–10× In) but lower than a Z-curve (2–3× In). For a panel builder wiring a 10 A motor starter or a control transformer, the K-curve avoids nuisance trips during the inrush event while still providing short-circuit protection. The thermal element handles sustained overloads the same way as other curves — the difference is only in the magnetic instantaneous trip point.","metaTitle":"ABB S802U-K10 MCB S800 2P K 10A, DIN Rail Circuit Breaker","metaDescription":"ABB S802U-K10 MCB, S800 series, 2-pole, K-curve, 10 A.
