The 3 kA breaking capacity per EN 60898 at 240 V AC covers standard domestic supply fault levels; for higher prospective short-circuit currents you'd step up to a higher-rated SENTRON variant. B-curve trip: magnetic release between 3 and 5 times rated current (75–125 A for this 25 A unit). That suits cable protection and general-purpose loads with no heavy motor start — lighting, socket outlets, control transformers. The 1P+N pole count means it occupies 2 width units (36 mm on a standard DIN rail) and includes a switched neutral, which is required in some regional wiring regulations for single-phase final circuits. Overvoltage category 3 and energy limiting class 3 confirm it's designed for fixed-installation downstream of the utility meter, not for equipment-level protection. ## Panel integration Installation depth is 55 mm, which fits standard distribution board enclosures. Neutral conductor switching is built in, so no external neutral link is needed downstream of the breaker.","metaTitle":"Siemens SENTRON 5SQ2560-0KA25 MCB, 2-Pole 1P+N, B Curve, 25","metaDescription":"Siemens SENTRON 5SQ2560-0KA25 miniature circuit breaker, 2-pole 1P+N, B tripping curve, 25 A rated current, 3 kA breaking capacity per EN 60898, 240 V AC.
