ABB 2CDS251001R0254 S201-C25 1P 25A 6kA C-Curve Miniature Circuit Breaker

The ABB S201-C25 miniature circuit breaker (SKU: 2CDS251001R0254) is a single-pole, 25 A, 6 kA breaking capacity MCB from the ABB S200 series, designed for overcurrent and short-circuit protection in residential, commercial, and light industrial distribution boards. The S201-C25 features a C-curve tripping characteristic, making it ideal for loads with moderate inrush currents such as motors, transformers, and fluorescent lighting circuits. DIN-rail mounted and rated for 230/400 V AC, it delivers reliable protection in a compact 17.5 mm wide profile.
