The Siemens 5SL6332-7MB is a SENTRON miniature circuit breaker, 3-pole, C-curve, rated 32 A with a 6 kA breaking capacity per EN 60898 at 400 V AC.
Lifecycle status is Active per the manufacturer, so this is a current-production part — no last-time-buy window, no obsolescence risk on a new BOM line.
The C-curve (tripping characteristic class C) means the breaker holds 5–10× rated current for short periods before instant tripping — the standard choice for motor-starter and lighting circuits where inrush is moderate. The 6 kA breaking capacity at 400 V AC (per EN 60898) covers most residential and light-commercial fault levels; for higher available fault current, the sibling 5SL4363-7 offers 10 kA per both EN 60898 and IEC 60947-2, at the same 3-pole 32 A C-curve rating and identical 54 mm footprint.
Ambient range -40 to 75 °C covers most indoor and sheltered outdoor cabinets. Accepts supplementary auxiliary devices (shunt trip, alarm switch, auxiliary contact) on the right side.
Power loss per pole at rated current in hot state is 2.5 W — 7.5 W total for the 3-pole assembly, relevant for thermal budgeting in a multi-breaker panel. Halogen-free and silicon-free construction; sealable option available.
