Product details

32 A, Trip Curve B, 1-Pole — DIN Rail Breaker

Rated operational voltage is 400/690 VAC and 125 VDC, with a frequency of 50/60 Hz. The interrupting rating reaches 50 kA at 230 VAC — that is the fault-clearing capacity you need for high-available short-circuit current at the panel main or subfeed. It is not the right choice for motor circuits or transformer primaries — those need Curve C or D to ride through the inrush without nuisance tripping.

Panel Integration

Snaps onto standard DIN rail. The 1-pole footprint leaves adjacent slots free for additional poles or other breakers in the same distribution block.

Frequently asked questions

Will S801S-B32 drop into a panel that was specified around S201MUC-K2 without rewiring?

No — the S201MUC-K2 is a 2 A, Curve K breaker with a 6 kA interrupting rating and a 277 VAC/250 VDC rating. The S801S-B32 is 32 A, Curve B, 50 kA at 230 VAC. They are not drop-in substitutes; verify the load current and coordination study before swapping.
