The D-curve means it tolerates high inrush currents — typically motor, transformer, or welding loads — without nuisance tripping on startup. At 40 °C the continuous rating derates to 1.9 A, at 50 °C to 1.8 A, and at 60 °C to 1.7 A; if the panel runs hot, size up accordingly. Breaking capacity is 15 kA per EN 60898 and 50 kA per IEC 60947-2, so it handles substantial fault currents in industrial distribution. The 36 mm width (2 modular units) snaps onto standard DIN rail, and the quick-assembly fastening method means it clips in without tools. ## Where it goes This MCB is designed for mechanical engineering and industrial panel environments. It mounts in any position, with an installation depth of 70 mm and overall depth of 76 mm. IP20 with connected conductors — fine inside a closed enclosure, not for washdown zones. Pollution degree 3 and overvoltage category III suit it for fixed industrial installations where transient overvoltages are expected. The combined top and bottom terminals accept incoming feed from either direction, and the neutral conductor is not switched (2-pole, both poles protected).","metaTitle":"Siemens 5SY7202-8 SENTRON MCB, 2P D-curve 2A, 15/50kA","metaDescription":"Siemens 5SY7202-8 SENTRON miniature circuit breaker, 2-pole, D characteristic, 2 A rated current, 15 kA (EN 60898) / 50 kA (IEC 60947-2) breaking capacity.
