The 10 kA breaking capacity (per EN 60898) tells you it can safely interrupt a fault current up to that level at 400 V AC without welding or failing; that's the standard rating for most industrial panelboards and sub-distribution boards. ## Where it goes and how it fits This breaker snaps onto a DIN rail (35 mm) and occupies 2 modular width units (36 mm total). Depth is 76 mm, so it clears a standard 80 mm deep enclosure without the cover hitting the handle. Mounting position is any, which helps when the panel layout gets tight.","metaTitle":"Siemens 5SY4232-8FA SENTRON MCB, 2P 32A D Curve, 10kA","metaDescription":"Siemens 5SY4232-8FA SENTRON miniature circuit breaker, 2-pole 32A D-curve, 10kA breaking capacity per EN 60898.
