The B-curve means it trips between 3 and 5 times rated current — designed for resistive and general-purpose loads where inrush is moderate, such as lighting circuits, control transformers, and small motor feeders in industrial panels. The 6 kA SCCR at 440 V AC ensures it safely interrupts fault currents up to that level without cascading upstream, meeting the coordination requirements of a typical distribution board. At 40 °C the continuous rating drops to 15.04 A, and at 50 °C to 14.02 A — so if the panel runs hot, the load must be derated accordingly. The 2-pole design switches both phase and neutral, but the neutral conductor is not switched (neutral conductor switching: No), meaning the neutral bar is through-wired and the breaker only opens the line side. ## Where it is used This MCB is intended for mechanical engineering and industrial applications, per its suitability listing. It mounts on a DIN rail (quick assembly system) in any position, with an installation depth of 70 mm and overall depth of 76 mm. The 36 mm width (2 modular units) fits standard enclosure cutouts. The IP20 rating with connected conductors means it is protected against finger contact but not against moisture — suitable for indoor panel installation, not washdown areas. The combined terminal at top and bottom accepts both busbar and conductor connections, simplifying panel wiring.","metaTitle":"Siemens 5SY6216-6CC SENTRON MCB, 2P B-16A 6kA 440V","metaDescription":"Siemens SENTRON 5SY6216-6CC miniature circuit breaker, 2-pole, B-curve, 16 A rated at 40 °C, 6 kA breaking capacity per EN 60898.
