ABB 2CDS271001R0504 S201M-C50 1P 50A 10kA C-Curve Miniature Circuit Breaker

The ABB S201M-C50 (SKU: 2CDS271001R0504) is a 1-pole, 50 A, 10 kA breaking capacity miniature circuit breaker from the S200M series, designed for reliable overcurrent and short-circuit protection in industrial control panels and distribution boards operating at 230/400 V AC. The S201M-C50 features a C-curve tripping characteristic, making it ideal for loads with moderate inrush currents such as motors, transformers, and general industrial equipment.
