ABB 2CDS271001R0254 S201M-C25 1P 25A 10kA C-Curve 230/400V AC Miniature Circuit Breaker

The ABB S201M-C25 miniature circuit breaker (SKU: 2CDS271001R0254) is a high-performance 1-pole MCB rated at 25A with a breaking capacity of 10kA at 230/400V AC, designed for reliable overcurrent and short-circuit protection in industrial and commercial control panels. Part of the S200M series, the S201M-C25 features a C-curve tripping characteristic suited for loads with moderate inrush currents such as motors, transformers, and general distribution circuits. Its compact 17.5mm width makes it ideal for space-critical DIN rail installations.
