The 3 kA breaking capacity per EN 60898 at 240 V AC covers most residential and light commercial distribution boards — but if your panel's prospective short-circuit current exceeds 3 kA, step up to the 6 kA or 10 kA variants in the same SENTRON family. Two modular width units at 18 mm each means this breaker occupies 36 mm of DIN-rail space — standard for a 1P+N device with neutral switching. Installation depth is 55 mm, shallower than the 70 mm typical of the 5SU series RCBOs, so it leaves more wiring room in shallow enclosures. Overvoltage category III confirms it's rated for fixed-installation downstream of the utility meter, not for equipment-level protection.","metaTitle":"SENTRON 5SQ2570-0KA02 Circuit Breaker, 2A C-Curve 1P+N 3kA","metaDescription":"SENTRON 5SQ2570-0KA02 circuit breaker, 2A rated current, C tripping characteristic, 1P+N poles, 3kA breaking capacity per EN 60898 at 240V AC.

That's the standard for residential and light commercial distribution boards; verify your prospective short-circuit current stays under this limit."},{"question":"Does 5SQ2570-0KA02 switch the neutral?","answer":"Yes, it has neutral conductor switching — the 1P+N pole configuration means both phase and neutral are opened when the breaker trips or is manually switched off."},{"question":"Where can I buy 5SQ2570-0KA02 and how is it quoted?","answer":"Sourced to order against an RFQ through independent distribution.

The 5SU9304-1KK32 is an RCBO with 32 A rating and 10 kA breaking capacity, while the 5SQ2570-0KA02 is a 2 A plain MCB with 3 kA. Both are 2-pole 1P+N and fit the same DIN-rail footprint, but the ratings and protection functions are fundamentally different."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SQ2570-0KA02","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/5SQ2570-0KA02 when reusing this data.
