Siemens 5SY7214-8 SENTRON MCB, 2P D 0.3A, 15kA EN

Rated 0.3 A at 35 °C, it protects against short-circuit and overload in circuits with high inrush currents — typical for motor starters, transformers, or power supplies where a B- or C-curve would nuisance-trip. Installation depth is 70 mm; the total depth with terminals is 76 mm. Any mounting position is permitted. Rated current derates with ambient temperature: 0.28 A at 40 °C, 0.27 A at 45 °C, 0.26 A at 50 °C, 0.25 A at 55 °C, and 0.24 A at 60 °C. The D-curve trips magnetically at 10–20× In, so it holds through the start-up spike of a small motor or capacitive load. Sealable, halogen-free, silicon-free. Touch protection on the terminals. Suitability marked for mechanical engineering and industry per the manufacturer.
