  • Description

The ABB 2CDS381001R0504 is an S301P-C50 miniature circuit breaker rated 50 A, 1-pole, with a C tripping characteristic, part of ABB's industrial-duty System pro M compact S300P range. Its IEC 60898-1 breaking capacity (Icn) is 15 kA, lower than the smaller-current S301P-C variants' 25 kA, while the IEC 60947-2 Icu reaches 100 kA at 230/240 V AC.

Selection Notes

The Icn drops from 25 kA to 15 kA once the S301P-C range reaches this current level, so fault-current studies at 50 A should use the 15 kA IEC 60898-1 figure rather than the higher IEC 60947-2 Icu rating. At 50 A this breaker suits a sub-distribution branch rather than a final small-load circuit. Where upstream short-circuit currents exceed 15 kA, back it up with a current-limiting device upstream rather than relying on this breaker alone.
