The B-curve means it trips between 3 and 5 times rated current — designed for resistive and lighting loads where inrush is low, not for motor starting or transformer primaries. The 15 kA breaking capacity per EN 60898 covers most commercial and light industrial panelboards; the 25 kA rating per IEC 60947-2 gives headroom for higher-fault installations where the upstream transformer is close. The 25 A rating is the continuous current at 35 °C ambient. At 40 °C it derates to 23.48 A, at 50 °C to 21.85 A, and at 60 °C to 20.1 A. The 36 mm width (2 modular units) snaps onto a DIN rail; depth is 76 mm, height 90 mm. Mounting position is any. IP20 with connected conductors means it's protected against finger contact but not moisture — suitable for dry indoor panels only, not washdown or outdoor locations. Overvoltage category III and pollution degree 3 confirm it's rated for fixed installation in industrial environments where transients are common. ## Panel integration and compliance The breaker mounts on a DIN rail via the quick assembly system — no tools needed for installation or removal. The combined terminal top and bottom accept copper conductors; the sealable feature allows locking in the OFF position for lockout/tagout procedures. Halogen-free and silicon-free construction matters for clean-room or sensitive electronic environments where outgassing could cause contact corrosion. Compliance documentation covers IEC 60898 and IEC 60947-2 as cited; the product designation follows IEC 81346-2 and DIN EN 61346-2 letter code F (protective device). Touch protection is built into the design — no additional finger-safe shrouds needed for standard panel wiring.","metaTitle":"Siemens 5SY7525-6 SENTRON MCB, 25 A, B-Curve, 2-Pole, 15/25","metaDescription":"Siemens 5SY7525-6 SENTRON miniature circuit breaker, 25 A rated, B-curve, 2-pole (1P+N), 15 kA per EN 60898 / 25 kA per IEC 60947-2.
