ABB 2CDS253001R0164 S203-C16 3P 16A 6kA Curve-C DIN-Rail Miniature Circuit Breaker

The ABB S203-C16 miniature circuit breaker (SKU: 2CDS253001R0164) is a 3-pole, 16A, 6kA breaking capacity MCB from the S200 series, designed for reliable overcurrent and short-circuit protection in industrial control panels and building distribution boards. Rated at 230/400V AC with a Type C tripping curve, the S203-C16 suits loads with moderate inrush currents such as motors, transformers, and mixed resistive-inductive circuits. DIN-rail mounting ensures fast, tool-efficient installation.
