The ABB S201-C32NA is a 1P+N miniature circuit breaker with a C-curve trip characteristic, rated at 32 A and 480Y/277 V. It protects branch circuits in final distribution boards, sized for general-purpose loads like lighting and small motor circuits where moderate inrush is expected — the C-curve holds through short-duration starting currents up to 5–10× rated, then clears on a hard fault.
Mounts on standard DIN rail in the distribution board. The 1P+N format occupies one module width plus the neutral pole, saving panel space compared to a 2-pole breaker when only the live needs overcurrent protection. Rated 480Y/277 V makes it suitable for 277/480 V wye systems common in North American commercial lighting panels.
