ABB 2CDS384001R0104 S304P-C10 4P 10A 25kA DIN Rail Miniature Circuit Breaker (MCB)

Rated at 10 A, the ABB 2CDS384001R0104 (S304P-C10) is a 4-pole S300P miniature circuit breaker with Curve C tripping and a 25 kA breaking capacity at 415 V AC. Built to IEC/EN 60898-1 and IEC/EN 60947-2 and listed to UL 1077 at 10 kA / 480Y/277 V AC, it switches and protects DIN-rail feeder and branch circuits.

Selection Notes

The 10 A rating sits in the lower-mid range of the S304P-C family, where Icn holds at 25 kA at 415 V AC up to 25 A before dropping as the frame current rises further. That 25 kA figure covers most LV sub-distribution boards without needing a current-limiting upstream device. Curve C's 5-10 x In magnetic trip threshold suits loads with moderate inrush - small motors, transformers, ballasts - rather than purely resistive circuits, where Curve B would be the tighter choice. The 4-pole configuration switches all three phases plus the neutral, which is needed on TN-C-S or TT systems where the neutral must also be isolated.
