REFERENCE MATERIAL
Check the document’s model and revision before use.
5SY4332-8 is a Siemens SENTRON D32 miniature circuit breaker with three poles. It is rated for 400 V AC and has a 10 kA breaking-capacity rating under EN 60898. Its 32 A current rating and D tripping characteristic must match the protected circuit.
Start with the circuit design. A matching pole count or enclosure size does not make a different ampere rating or tripping curve an interchangeable replacement.

These are separate order numbers in this catalogue. Check the current and characteristic shown for each model.
The 10 kA figure is a short-circuit breaking-capacity rating under EN 60898. It is not the continuous load current. IEC 60947-2 and UL 1077 entries in the data sheet use their own ratings and test conditions; use the entry that applies to the installation.
The marked 32 A rating is not an unconditional load allowance at every cabinet temperature. The exact data sheet provides temperature-dependent operational currents. Check the conductor size, terminal tightening requirements and available fault current as part of circuit selection.
Check the dimension drawing when replacing a breaker in an existing enclosure. The 70 mm installation-depth designation is a different measurement from the overall product depth. Reserve space for conductors and any side-mounted auxiliary device.
Only after confirming the required tripping characteristic and the other circuit ratings. B, C and D identify different magnetic tripping behaviour; the ampere number alone is not sufficient.
This model has three poles. Do not treat it as a three-pole-plus-neutral device; select a device with the required neutral arrangement when the circuit needs one.
