The C-curve means it holds 5–10× rated current for short overloads before the magnetic trip fires — standard for motor and light industrial loads where inrush isn't extreme. At 40 °C ambient the rated current derates to 0.28 A; at 55 °C it drops to 0.25 A. Mounting position any, so vertical or horizontal busbars work. Touch protection built in.","metaTitle":"Siemens 5SL3214-7 SENTRON MCB, 2P C 0.3A 400V 4.5kA","metaDescription":"Siemens 5SL3214-7 SENTRON miniature circuit breaker, 2-pole C-curve 0.3A, 400V AC, 4.5kA breaking capacity per IEC/EN 60898 & 60947-2.
