The C-curve (trips between 5× and 10× In) is the standard choice for general-purpose branch circuits feeding moderate inrush loads — think lighting banks, small motor starters, or control transformers — where the magnetic trip needs to ride through a short current surge without nuisance opening. The 6 kA breaking capacity per EN 60898 (and also 6 kA per IEC 60947-2) means it can safely interrupt a fault current up to that level on a 400 V AC supply; in a residential or light commercial panel with a typical prospective short-circuit current under 6 kA, this breaker provides adequate fault clearance without cascading upstream. The 32 A rating is the continuous current at 30 °C ambient. At 40 °C it derates to 29.56 A, at 45 °C to 28.16 A, and at 55 °C to 25.48 A — so if the breaker lives in a warm enclosure or near other heat sources, size the load accordingly. The IP20 rating (with connected conductors) is typical for enclosed panel mounting; the breaker is not intended for wet or dusty environments without an outer enclosure. Pollution degree 2 and overvoltage category III confirm it is designed for fixed-installation distribution boards where transient overvoltages are controlled by upstream SPDs. ## Panel integration and mounting The 5SL6332-7BB occupies 3 modular width units (each 18 mm wide, so 54 mm total) on a standard DIN rail. Depth is 76 mm, installation depth 70 mm. It can be mounted in any position, which simplifies layout in crowded enclosures. The sealable design allows the installer to lock the toggle position after commissioning — useful for tamper-proofing a critical circuit in a shared panel.","metaTitle":"Siemens 5SL6332-7BB SENTRON MCB, 3P C 32A 6kA","metaDescription":"Siemens SENTRON 5SL6332-7BB miniature circuit breaker, 3-pole, C-curve, 32 A, 6 kA per EN 60898, 400 V AC.
