It breaks 6 kA per EN 60898 and 30 kA per IEC 60947-2, with a DC rating of 15 kA per IEC 60947-2 and a UL 1077 interrupting capacity of 5 kA. This is the part for a 0.3 A motor or control circuit branch that needs a C-curve — moderate inrush tolerance — and fits a 2-module-wide DIN slot. The 0.3 A rating at 35 °C derates to 0.28 A at 40 °C, 0.27 A at 45 °C, 0.26 A at 50 °C, and 0.25 A at 55 °C — so if your panel ambient runs 50 °C, the breaker handles a continuous load of 0.26 A, not 0.3 A. The C characteristic means magnetic trip occurs at 5–10× In, so it holds motor inrush but clears a hard short fast. Sealable and halogen-free, silicon-free — suitable for environments where outgassing matters. Ambient temperature range -40 to 75 °C, with humidity limits per the surrounding temperature influence.","metaTitle":"Siemens 5SY6214-7 MCB, C-curve 2-pole 0.3 A, 6 kA","metaDescription":"Siemens SENTRON 5SY6214-7 miniature circuit breaker, C characteristic, 2-pole, 0.3 A rated at 35 °C, 400 V AC, 6 kA breaking capacity per EN 60898.
