The 10 kA breaking capacity (identical per EN 60898 and IEC 60947-2) means it can safely interrupt a fault current up to that level without welding contacts or cascading upstream, which covers the vast majority of utility-side fault levels in commercial and residential distribution boards. Occupies 2 modular width units (36 mm wide, 90 mm tall, 76 mm deep, 70 mm installation depth). IP20 with connected conductors — fine inside an enclosed distribution board or panel, not for wet or exposed locations. Sealable, halogen-free, silicon-free construction suits environments where outgassing or contamination is a concern, such as clean rooms or food processing areas. ## Installation flexibility Rated for overvoltage category III, pollution degree 2, and a mechanical service life of 10 000 operating cycles typical.","metaTitle":"Siemens SENTRON 5SL4225-6 MCB, 2P B 25A 400V 10kA","metaDescription":"Siemens SENTRON 5SL4225-6 miniature circuit breaker, 2-pole, B-curve, 25 A, 400 V AC, 10 kA breaking capacity per EN 60898 & IEC 60947-2.

It occupies 3 modular width units (54 mm) instead of 2 (36 mm). The C-curve trips at 5–10× rated current, suited for motor and transformer loads with higher inrush. Both share the same 10 kA breaking capacity, 400 V AC rating, and 76 mm depth, so they fit the same panel depth but not the same pole count or curve application."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL4225-6","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/5SL4225-6 when reusing this data.
