It's built for 400 V AC three-phase circuits at 50 Hz, with a maximum multi-phase voltage of 440 V. The C-curve means the magnetic trip fires at 5–10× rated current — 8–16 A for this 1.6 A unit — so it's sized for moderate inrush loads like small motor starters or lighting banks where you need to ride through the start surge without nuisance tripping. The derating table tells you what happens when the panel gets warm: at 40 °C ambient the breaker is good for 1.54 A, at 55 °C it drops to 1.43 A. If your enclosure runs hot, you either downrate the load or move up one frame size. Mounts in any position — upright, sideways, inverted — without derating the trip curve. Pollution degree 2 (normal industrial atmosphere, non-conductive dust) and overvoltage category III (permanent connection to the mains) cover the standard panel environment. The IP20 rating with conductors connected is typical for enclosed distribution boards; keep the front cover on during washdown. Touch protection is built into the terminals.","metaTitle":"Siemens 5SL6315-7BB SENTRON MCB, 3P C-curve 1.6A 6kA","metaDescription":"Siemens 5SL6315-7BB SENTRON 3-pole miniature circuit breaker, C-curve 1.6 A, 6 kA breaking capacity per EN 60898, 400 V AC.
