The only difference is the current rating: 10 A on this code versus 1.6 A on the sibling. Both share the identical mechanical footprint and DIN-rail clip, so a panel specified around the 1.6 A version accepts the 10 A unit without rewiring. The swap is valid only if the downstream load and cable sizing support the higher rating. The MCB carries an IP20 protection class (finger-safe terminals, no washdown rating). Overvoltage category 3 and energy limiting class 3 are specified per IEC/EN 60664 and EN 60898 respectively. Neutral conductor switching is not built in — this is a live-pole-only device. For compliance documentation (CE marking, RoHS, REACH, UL listing), the manufacturer's declaration applies to the SENTRON T55 series; confirm the specific certificate for this order code at quote time.","metaTitle":"Siemens SENTRON 5SQ2170-0KA10 MCB, 1P C-curve 10A, 3kA","metaDescription":"Siemens SENTRON 5SQ2170-0KA10 miniature circuit breaker, 1-pole, C-curve, 10 A rated current, 3 kA breaking capacity per EN 60898, 240 V AC/DC.
