The 2-pole design switches both phase and neutral (neutral conductor switching is built in), so it fits single-phase final subcircuits where you want full isolation on both conductors. At 55 mm installation depth and 2 width units, it occupies standard DIN-rail space; IP20 finger-safe terminals are fine for enclosed distribution boards.","metaTitle":"SENTRON 5SQ2260-0KA25 MCB 2P B 25A 3kA 400V AC/DC","metaDescription":"SENTRON 5SQ2260-0KA25 circuit breaker, 2-pole, B-curve, 25 A, 3 kA breaking capacity per EN 60898, 400 V AC/DC.
