Breaking capacity: 15 kA per EN 60898, 25 kA per IEC 60947-2. For a 32 A MCB on a 400 V distribution board, the 25 kA figure under 60947-2 is the one that matters for industrial SCCR coordination — it tells you the breaker can clear a fault up to 25 kA without welding its contacts or rupturing the housing. Rated current derates with ambient temperature: 32 A at 35 °C, 30.46 A at 40 °C, 28 A at 55 °C, 27.14 A at 60 °C.
Any mounting position works.
15 kA per EN 60898 and 25 kA per IEC 60947-2. The 60947-2 figure is the one to use for industrial panel SCCR calculations.
The 5SY7132-8 is a 1-pole, 32 A D-curve MCB; the 5SY7140-8CC is a different rating and characteristic. Both share the same 18 mm width and DIN-rail mounting, so the physical footprint is identical — no rewiring needed for the panel cutout, but the electrical ratings differ. Verify the load and coordination requirements before substituting.
