ABB 2CDS271001R0634 S201M-C63 1P 63A 10kA C-Curve Miniature Circuit Breaker

The ABB S201M-C63 (SKU: 2CDS271001R0634) is a 1-pole, 63 A miniature circuit breaker (MCB) from the S200M series, designed for overcurrent and short-circuit protection in industrial and commercial installations. Rated at 230/400 V AC with a breaking capacity of 10 kA and a Type C tripping curve, the S201M-C63 delivers robust protection for loads with moderate inrush currents such as motors, transformers, and distribution circuits. Its compact 17.5 mm width makes it ideal for space-constrained control panels and DIN rail assemblies.
