- Description
The ABB 2CDS272061R0984 is an S202M-C0.5UC miniature circuit breaker, 2-pole, from ABB's System pro M compact S200MUC range, rated 0.5 A with a C tripping characteristic for AC or DC circuits. Rated to 400 V AC / 440 V DC under IEC 60898-1, it carries a 10 kA breaking capacity (AC) and switches both poles together for double-pole protection or L+N disconnection.

Selection Notes
Switching both poles together makes this 2-pole device suitable for L+N disconnection on AC circuits or plus/minus disconnection on a DC bus, rather than protecting two independent single-phase circuits. The C curve trips instantaneously at 5-10x In, adequate margin even at this low 0.5 A rating. Within the S202M-C 2-pole frame, current ratings run from 0.5 A to 13 A in this batch; match the rating to the actual branch current rather than this smallest value.
