The Siemens 5SL3332-6 is a 3-pole SENTRON miniature circuit breaker with B tripping characteristic, rated 32 A at 400 V AC and a breaking capacity of 4.5 kA per IEC 60898 and IEC 60947-2.
Snap-on DIN-rail mount, any position. Accepts up to 440 V AC multi-phase. No neutral conductor switching — this is a straight 3-pole overcurrent device. Suitable for residential buildings and infrastructure applications.
The 5SL3332-6 is rated 4.5 kA breaking capacity per both IEC 60898 and IEC 60947-2 at 400 V AC.
Operating ambient temperature range is -40 °C to 75 °C, with derated current at elevated temperatures (30.45 A at 40 °C, 29.76 A at 45 °C, 27.97 A at 55 °C).
The 5SL3332-6 is a 3-pole B-characteristic 32 A MCB; the 5SL4120-7CC is a different pole/current variant. Both share the same 5SL DIN-rail footprint and modular width per pole, so mechanical fit is identical — but verify the rating and characteristic match your circuit design before substitution.
