The E tripping characteristic means it's designed for selective coordination — it holds through short-duration overloads typical of transformer inrush or motor starting, then clears fast on a hard fault. Occupies 4.5 modular width units — that's 81 mm of rail space at the standard 18 mm per unit. Depth is 76.3 mm, height 128 mm. The enclosure depth matches the breaker body; no extra projection for the toggle. Infeed at the box terminal is standard, and supply position can be any orientation. IP40 with connected conductors — fine for enclosed distribution boards. Integrated locking slide accepts a padlock, wire seal, or cable ties for lockout/tagout. Sealable per the spec, so it meets most site isolation requirements. At 40 °C it's 23.75 A; at 50 °C it's 22.5 A; at 55 °C it's 21.875 A. That's the number to use for the BOM, not the 25 A label.","metaTitle":"Siemens 5SP3825-3 SENTRON MCB, 3P 25A 25kA Type E","metaDescription":"Siemens 5SP3825-3 SENTRON miniature circuit breaker, 3-pole, 25 A, 25 kA breaking capacity, characteristic E, 400 V AC.

The 5SP3825-3 occupies 4.5 MW units; verify the 5SJ6325-7RC's width before assuming a drop-in fit. Terminal capacity (50 mm² max) and supply position flexibility are similar, but coordination studies would need re-running due to the different trip curve."},{"question":"What is 5SP3825-3's listed depth?","answer":"Depth is 76.3 mm, same as the enclosure depth.
