It carries a 6 kA breaking capacity under both EN 60898 and IEC 60947-2, making it suitable for residential and infrastructure branch-circuit protection where the B-curve's magnetic trip between 3–5× In provides fast clearing on short circuits while tolerating moderate inrush from lighting and resistive loads. ## B-Curve Trip and Breaking Capacity The B-curve characteristic (magnetic release at 3–5× In) means the 25 A rating trips magnetically between 75 A and 125 A — a good fit for general-purpose circuits feeding resistive loads, lighting, or small motor loads where inrush stays below that threshold. The 6 kA interrupting rating at 400 V AC, certified to both EN 60898 (household standard) and IEC 60947-2 (industrial standard), covers most commercial and light-industrial fault levels. Each pole dissipates 2.8 W in the hot operating state at rated current — a figure to consider when calculating thermal rise in a densely populated enclosure. The 10 000 mechanical operating cycles typical service life is standard for this class and sufficient for most switching duties short of daily manual operation. ## Panel Fit and Environmental Range Dimensions: 90 mm high, 36 mm wide (2 MW), 76 mm deep with 70 mm installation depth behind the panel. Halogen-free and silicon-free construction meets low-smoke, zero-halogen requirements for public buildings and infrastructure projects. Sealable terminals allow tamper-proofing after commissioning.","metaTitle":"Siemens 5SL6225-6 SENTRON MCB, 2-Pole B 25A 6kA","metaDescription":"Siemens 5SL6225-6 SENTRON miniature circuit breaker, 2-pole, B-curve, 25 A, 6 kA per EN 60898/IEC 60947-2, 400 V AC.

The 5SL4363-7 is a 3-pole C-curve unit occupying 3 MW (54 mm) versus the 5SL6225-6's 2-pole B-curve at 2 MW (36 mm). The pole count, trip characteristic, and width differ, so a panel designed for the 5SL4363-7 would require busbar and wiring changes to accept the 5SL6225-6."},{"question":"What compliance documentation is available for the 5SL6225-6?","answer":"The 5SL6225-6 is certified to EN 60898 and IEC 60947-2, carries overvoltage category III and pollution degree 2 ratings, and is halogen-free and silicon-free.
