This breaker switches both poles (2-pole, switched neutral per). It accepts AC or DC supply voltage, though the 3 kA rating is specific to AC per EN 60898. ## Panel integration The 2 width units (36 mm) and 55 mm depth leave room alongside other SENTRON modules in a standard enclosure. Neutral conductor switching is built in, so no separate neutral bar needed downstream of this breaker in a 2-wire circuit.","metaTitle":"SENTRON 5SQ2270-0KA32 MCB, 2-pole C-curve 32A, 3kA","metaDescription":"Siemens SENTRON 5SQ2270-0KA32 miniature circuit breaker, 2-pole, C-curve, 32 A, 400 V AC, 3 kA breaking capacity per EN 60898.
