32 A, D-curve MCB for motor and transformer circuits
Per the datasheet, interrupting capacity stands at 15 kA at 400 VAC and 10 kA at DC, giving selectivity headroom for sub-distribution boards with fault currents in that range.
The 3-pole footprint occupies three modular units (17.5 mm per pole) — measure the available space before ordering, as a full 52.5 mm width is needed. Spring-cage terminals accept 1–25 mm² conductors; strip length of 12–14 mm avoids whiskers under the cage. No busbar bridging required for multi-pole connection; the internal link is factory-fitted.
For selective coordination with downstream MCBs, the D-curve's higher magnetic threshold (10–20× In) provides better discrimination than a C-curve when feeding sub-circuits with motor loads. Verify the let-through energy (I²t) against upstream fuse or MCCB curves using the manufacturer's selectivity tables.
