ABB 2CDS382001R0324 S302P-C32 2P 32A 20kA DIN Rail Miniature Circuit Breaker (MCB)

The ABB 2CDS382001R0324 is a 2-pole S300P miniature circuit breaker (S302P-C32) rated at 32 A with a Curve C tripping characteristic and a 20 kA breaking capacity at 415 V AC. It protects DIN-rail circuits against overload and short circuits according to IEC/EN 60898-1 and IEC/EN 60947-2, and carries a UL 1077 interrupting rating of 10 kA at 480Y/277 V AC.

Selection Notes

Curve C trips magnetically at 5-10 x In, making the 2CDS382001R0324 suited to loads with moderate inrush (small motors, transformers, lighting ballasts) rather than purely resistive circuits, where Curve B would nuisance-trip on switch-on. Its 20 kA Icn at 415 V AC covers typical industrial sub-distribution boards; within the S302P-C family the 50 A and 63 A frames step down to 15 kA Icn, so this 32 A / 20 kA combination is the better fit wherever the prospective fault current at the board exceeds 15 kA but stays at or below 20 kA. The 2-pole configuration switches both line conductors, which is required when the neutral must also be isolated on a TN-C-S or IT system.
