That IEC number is the one your arc-flash study cares about when you're coordinating downstream loads in a panel with a transformer feeding high available current. ## Thermal derating and ambient limits At 35 °C ambient the 5SY7432-6 carries its full 32 A. At 40 °C it derates to 30.72 A, at 50 °C to 29.41 A, and at 60 °C to 28.03 A. The combined terminals on top and bottom accept incoming and outgoing conductors in the same clamp — saves a busbar or a jumper in multi-pole setups. ## Construction and environment Halogen-free and silicon-free construction avoids corrosive off-gassing in a fire and won't contaminate sensitive contacts or optics nearby.","metaTitle":"Siemens 5SY7432-6 SENTRON MCB, 4P, 32A, B-Curve, 15kA EN 608","metaDescription":"Siemens 5SY7432-6 SENTRON 4P miniature circuit breaker, 32A rated, B characteristic, 15 kA (EN 60898) / 25 kA (IEC 60947-2).
