ABB 2CDS381001R0024 S301P-C2 1P 2A 25kA DIN Rail Miniature Circuit Breaker (MCB)

Rated at 2 A, the ABB 2CDS381001R0024 is an S301P-C2 miniature circuit breaker from ABB's System pro M compact S300P industrial range, built for 1-pole AC or DC overload and short-circuit protection with a C tripping characteristic. It carries a 25 kA breaking capacity (Icn) under IEC 60898-1 and an IEC 60947-2 Icu rating of 100 kA at 230/240 V AC, reflecting its heavier industrial-grade construction.

Certifications & Standards

• IEC/EN 60898-1
• IEC/EN 60947-2
• UL 1077
• CSA 22.2 No. 235

Selection Notes

The 100 kA Icu under IEC 60947-2 reflects industrial-type testing current, not the figure used for residential compliance; the 25 kA Icn under IEC 60898-1 is what applies where domestic/light-commercial standards govern the installation. At 2 A this variant protects low-current control or instrumentation circuits rather than a power branch. The S301P-C series in this frame spans from 2 A up to 63 A, with the Icn dropping to 15 kA on the higher-current variants; match the rating to the branch's design current and short-circuit exposure rather than defaulting to this lowest value.
