ABB S282UC-K10 Miniature Circuit Breaker, 10 A, 2 Pole, Curv

The 10 A rating and Trip Curve K mean this breaker is optimized for DC circuits with inductive loads — motors, solenoids, contactor coils — where inrush currents are higher than resistive loads. Curve K trips faster than Curve C on moderate overloads but still allows starting surges. The 500 VDC rating covers most industrial DC bus voltages (common 400–480 VDC systems) with headroom. Two poles let you break both the positive and negative legs of a DC circuit in one unit, which is typical for ungrounded DC systems in control panels and battery-backed supplies. DIN-rail mounting means it clips into the same footprint as standard ABB S200 series breakers — no special adapters needed.
