Rated 4 A at 240 V AC with a C-curve trip characteristic, it handles the moderate inrush of lighting banks, small transformers, and motorized valve actuators without nuisance tripping. The 3 kA breaking capacity per EN 60898 covers most residential and light commercial final circuits; for higher fault levels you'd step up to an industrial-class device. ## Panel fit and integration Occupies 2 width units on a DIN rail. Installation depth is 55 mm. IP20 protection. ## Sourcing and lifecycle Current production. Standard SENTRON catalog item. Sourced and quoted to order against an RFQ.","metaTitle":"SENTRON 5SQ2570-0KA04 MCB, 2-pole C-curve 4A, 3kA","metaDescription":"SENTRON 5SQ2570-0KA04 miniature circuit breaker, 2-pole 1P+N, C-curve 4A, 3kA per EN 60898, 240V AC/DC.

The key difference is voltage: the -0KA04 is rated 240 V AC, while the -2YA04 is rated 400 V AC. If the panel is wired for 240 V single-phase with neutral, the -0KA04 fits without rewiring."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SQ2570-0KA04","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/5SQ2570-0KA04 when reusing this data.
