It's the kind of breaker you spec for motor-starting or high-inrush loads where a C-curve would nuisance-trip on the first cycle. The D characteristic means the magnetic trip fires at 10–20× In, so it holds through the locked-rotor draw of a small conveyor or compressor. ## Breaking capacity and what it means for your panel Two breaking-capacity ratings on this part — 15 kA per EN 60898, 25 kA per IEC 60947-2. The EN number is the one that governs for domestic / light commercial distribution boards; the IEC number matters when you're specifying into an industrial panel where the prospective fault current is higher. At 25 kA (IEC 60947-2), this breaker clears a bolted fault without welding its contacts or venting arc gas into the enclosure — that's the rating a site electrical engineer checks for SCCR headroom on the panel nameplate. ## DIN-rail fit and panel integration Two modular-width units wide (36 mm), 76 mm deep, 90 mm tall. Snaps onto standard DIN rail via the quick-assembly system — no tools needed for the rail mount, but the combined top and bottom terminals mean you'll want a screwdriver for the wiring. Mounting position is any, so you can lay it sideways in a shallow gland-plate layout if the enclosure depth is tight. Installation depth is 70 mm behind the panel face. ## Derating and environmental limits Rated 32 A at 35 °C ambient. At 45 °C it derates to 29.66 A; at 55 °C it's 28 A; at 60 °C it's 27.14 A. If your panel runs hot — say a packed enclosure with drives — you size the load to the 55 °C or 60 °C figure, not the 35 °C sticker. The breaker is halogen-free and silicon-free, which matters for outgassing-sensitive environments like medical or semiconductor fabs. Pollution degree 3 (conductive pollution or dry non-conductive that becomes conductive under condensation) — typical for industrial control panels without climate control.","metaTitle":"Siemens 5SY7232-8 SENTRON MCB, 2P D 32A 15kA EN 60898","metaDescription":"Siemens 5SY7232-8 SENTRON miniature circuit breaker, 2-pole, D-curve, 32 A rated at AC, 15 kA per EN 60898 / 25 kA per IEC 60947-2.
