It carries a breaking capacity of 6 kA per EN 60898 and 10 kA per IEC 60947-2 — the higher figure under the industrial standard means it can safely interrupt fault currents up to 10 kA in a panel environment, giving you headroom over the residential-grade rating. Two poles in a 36 mm wide housing (2 modular width units) means this breaker occupies two standard 18 mm DIN-rail slots. The 72 V DC maximum rating tells you this is primarily an AC device — it will switch DC control circuits up to 72 V, but the interrupting capacity on DC is not separately stated here. For DC-only applications, check the IEC 60947-2 DC rating on a dedicated DC-rated MCB. Solid conductor cross-section up to 35 mm² accepts the larger tails common in sub-distribution boards. Mechanical service life of 10,000 operating cycles is typical for this class of MCB — adequate for distribution switching, not intended for frequent motor-starting duty. Snap-on DIN-rail mounting for 400 V AC branch-circuit protection in commercial and light-industrial distribution boards. The 6 kA EN 60898 rating suits domestic and commercial final circuits; the 10 kA IEC 60947-2 rating covers industrial panel applications where higher prospective fault current is expected.","metaTitle":"Siemens 5SN6250-7CP MCB, 2-Pole, 400 V AC, 6 kA EN 60898","metaDescription":"Siemens 5SN6250-7CP miniature circuit breaker, 2-pole, 400 V AC rated, 6 kA per EN 60898, 10 kA per IEC 60947-2.

Depth and height are identical at 76 mm and 90 mm respectively, so panel depth clearance is the same."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SN6250-7CP","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/5SN6250-7CP when reusing this data.
