Breaking capacity is 4.5 kA per EN 60898 and 5 kA per IEC 60947-2 — that's the fault current it can safely interrupt without welding contacts or rupturing the case. For most domestic and light commercial panels with typical prospective short-circuit currents under 4.5 kA, that's adequate headroom. At 40 °C it derates to 30.45 A, at 45 °C to 29.76 A, and at 55 °C to 27.97 A — so if the breaker lives in a hot panel or next to other heat sources, factor that in. That's one unit wider than the 3-pole 5SL3340-7CC — so swapping a 3-pole for this 4-pole means freeing up one extra module space in the panel. For a BOM line that needs this exact 4-pole C 32 A breaker, the 5SL3432-7 is the order code to specify. Mounts in any position on standard DIN rail — no orientation restrictions. Pollution degree 2 (non-condensing, typical of normal indoor environments) and overvoltage category III suit it for fixed-installation distribution boards downstream of the main service entrance. Sealable, halogen-free, and silicon-free — so it can go into panels that need to meet low-smoke, zero-halogen material specs (like public buildings or transit infrastructure).","metaTitle":"Siemens 5SL3432-7 SENTRON MCB, 4-pole C 32 A, 400 V","metaDescription":"Siemens 5SL3432-7 SENTRON miniature circuit breaker, 4-pole, C-curve, 32 A at 400 V AC.
