It occupies 2 width units (36 mm) on a DIN rail and is designed for quick assembly in industrial control panels and mechanical engineering applications. The B-curve trips between 3 and 5 times rated current, making it suitable for protecting cable runs and resistive or lightly inductive loads where inrush is modest — typical for general-purpose branch circuits in a panel.","metaTitle":"Siemens 5SY4204-6CC11 SENTRON MCB, 2P, 4A, B-Curve, 10kA","metaDescription":"Siemens 5SY4204-6CC11 SENTRON miniature circuit breaker, 2-pole, 4 A, B characteristic, 10 kA breaking capacity per EN 60898.
