IP20 finger-safe terminals are standard for enclosed panel mounting. ## What the B-curve and 3 kA rating mean for fit At 10 A, the breaker will hold a continuous 10 A load and trip instantaneously between 30 A and 50 A. Overvoltage category 3 and energy limiting class 3 confirm it is rated for fixed-installation use and will limit let-through energy to protect downstream wiring. Snap-on DIN rail mount, 2 width units (36 mm at 18 mm/module). 55 mm installation depth fits standard 60 mm deep enclosures. The neutral pole is switched internally — no separate neutral bar needed downstream of this breaker. IP20 rated for enclosed panel use only.","metaTitle":"SENTRON 5SQ2260-0KA10 MCB, 2-Pole B 10A 3kA","metaDescription":"SENTRON 5SQ2260-0KA10 miniature circuit breaker, 2-pole, B-curve, 10 A, 3 kA per EN 60898, 400 V AC/DC.

The 5SQ2260-0KA10 is a B-curve 10 A breaker with neutral switching; the 5SQ2270-2YA04 is a C-curve 4 A breaker. The C-curve (5–10× In) suits motor or transformer loads with higher inrush; the B-curve fits general-purpose circuits. The 10 A rating on the 5SQ2260-0KA10 supports a higher continuous load than the 4 A peer."},{"question":"What is the number of poles on 5SQ2260-0KA10?","answer":"It is a 2-pole breaker (2P), switching both phase and neutral."},{"question":"What type of voltage does 5SQ2260-0KA10 support?","answer":"It is rated for AC/DC operation, 400 V AC at 50 Hz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SQ2260-0KA10","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SQ2260-0KA10 when reusing this data.
