It switches the neutral conductor as well as the line, per the product function. The 1 A rated current at AC and C-curve (magnetic trip at 5–10× In) suit it for protecting small inductive loads like contactor coils, signal transformers, or control-circuit branches — not motor feeders. Overvoltage category 3 and energy limiting class 3 are standard for final-circuit distribution panels. The 55 mm installation depth and 2 width units (roughly 36 mm at 18 mm per unit) fit standard DIN-rail enclosures. Neutral conductor switching is built in, so no external link is needed for the neutral pole.","metaTitle":"Siemens SENTRON 5SQ2270-0KA01 MCB, 2P, C, 1A, 3kA","metaDescription":"Siemens SENTRON 5SQ2270-0KA01 miniature circuit breaker, 2-pole, C-curve, 1 A, 3 kA per EN 60898/IEC 60947-2, 400 V AC, IP20.
