Siemens 5SL6332-7RC SENTRON MCB, 32 A, 3-pole, C-curve, 7.5

32 A C-curve MCB for distribution boards

It breaks fault currents up to 7.5 kA per EN 60898 at 415 V AC — that's the standard for most domestic and light commercial sub-distribution boards in Europe and markets following IEC 60898.

Mounting position any, so vertical or horizontal busbar feeds are fine. IP20 with conductors connected — normal for inside a locked panel; no washdown rating here.

The C characteristic means magnetic trip between 5× and 10× In (160–320 A for this 32 A unit), which is the standard choice for mixed resistive and light inductive loads in residential and commercial final circuits. Power loss per pole is 2.5 W at rated current in hot state — three poles together dissipate 7.5 W, so check the thermal budget if you're packing 24 of these in a row.
