Curve K is a magnetic-only trip characteristic with a narrow instantaneous trip band (typically 8–12x In), designed to ride through the inrush of inductive loads like solenoid valves, contactor coils, and small transformers while still providing short-circuit protection. The 25 A continuous rating governs the load it can carry in free air at 30 °C; derate per the manufacturer's thermal curve when ganged or enclosed. ## Panel integration Snap-on DIN rail mounting per EN 60715. The 2-pole footprint occupies two 17.5 mm modular spaces. Spring-cage terminals accept 0.2–25 mm² conductors; strip length 12 mm. Torque to 2.5 Nm. The busbar comb bridges across the line side for a common feed; verify the comb pitch matches the S800 series terminal spacing before ordering.","metaTitle":"S802S-K25 ABB High Perf MCB, 25A, Curve K, 2P, 50kA","metaDescription":"ABB S802S-K25 High Performance MCB, 25A, Trip Curve K, 2-pole, 230 VAC, 50 kA interrupting rating.
