The B-curve means it trips on overload between 3 and 5 times rated current — standard for protecting resistive or general-purpose loads like lighting, small heaters, or control transformers where inrush is low. The 6 kA breaking capacity tells you it can safely interrupt a fault current up to that level at the rated voltage, which is typical for final subcircuits in commercial or light-industrial distribution boards. ## Deployment context Snap-on mounting to standard 35 mm DIN rail inside a distribution board or sub-panel. The 4-pole form factor handles three-phase-plus-neutral circuits; the B-curve characteristic suits general-purpose final circuits where motor inrush is not a concern.","metaTitle":"Siemens 5SJ6432-6RC MCB, 4p 6kA 32A B Characteristic","metaDescription":"Siemens 5SJ6432-6RC 4-pole MCB, 32A B-curve, 6kA breaking capacity.
