Snap-on DIN-rail mount, 2 width units (36 mm at 18 mm/module). Installation depth is 55 mm from the rail face — standard for flush-mount distribution boards. IP20 finger-safe terminals; wire it into an enclosure if the environment is dusty or damp. Overvoltage category 3 and energy limiting class 3 mean it coordinates with downstream loads and upstream breakers in a typical TN or TT system.","metaTitle":"SENTRON 5SQ2570-0KA20 MCB, 1P+N, C-curve 20 A, 3 kA","metaDescription":"SENTRON 5SQ2570-0KA20 miniature circuit breaker, 1P+N, 20 A, C-curve, 3 kA per EN 60898, 240 V AC, 50 Hz.
