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.","metaTitle":"Siemens 5SY7214-8 SENTRON MCB, 2P D 0.3A, 15kA EN","metaDescription":"Siemens 5SY7214-8 SENTRON miniature circuit breaker, 2-pole, D-curve, 0.3 A rated, 15 kA (EN 60898) / 50 kA (IEC 60947-2) breaking capacity.
