The C-curve is the default for general-purpose commercial and light industrial loads — it holds through the 6–8x inrush of a 3 kW motor starting direct-on-line. Snap-on mounting to DIN rail, any position. Occupies 3 width units (54 mm). Terminal torque spec is 2.5 to 3 N·m — no special tooling needed. IP20 with connected conductors, touch-protected terminals. Sealable, halogen-free, silicon-free — suitable for food processing or clean-room environments where outgassing matters. Rated ambient temperature -25 to +45 °C, storage -40 to +75 °C. Overvoltage category 3, energy limiting class 3. The product designation follows DIN EN 61346-2 and DIN EN 81346-2 (function code F). No neutral conductor switching — this is a 3-pole breaker for 3-phase circuits only.","metaTitle":"Siemens 5SL3350-7 SENTRON MCB, 50A C-Curve 3P 4.5kA","metaDescription":"Siemens 5SL3350-7 SENTRON miniature circuit breaker, 50 A rated, C tripping characteristic, 3-pole, 4.5 kA breaking capacity per EN 60898/IEC 60947-2, 400 V AC.

Availability and current pricing are confirmed at quote time."},{"question":"What is the closest functional second-source to 5SL3350-7?","answer":"Within the SENTRON family, the 5SL6563-7BB is a peer with a higher breaking capacity (6 kA vs 4.5 kA) and a B-curve instead of C-curve. It shares the same 3-pole, 50 A rating and DIN-rail footprint, but the tripping characteristic differs — B-curve trips at 3-5x rated current, so it's better for resistive loads with no inrush. Verify selectivity coordination before substituting."},{"question":"Will 5SL3350-7 drop into a panel specified around 5SL6563-7BB without rewiring?","answer":"Yes, same 3-pole DIN-rail footprint, same 54 mm width (3 width units), same wire range 0.75–25 mm². No rewiring needed. The only difference is the tripping curve (C vs B) and breaking capacity (4.5 kA vs 6 kA), so check the fault level and load type before swapping."},{"question":"What compliance documentation does Siemens provide for 5SL3350-7?","answer":"Standard Siemens declaration of conformity covering RoHS, REACH, UL, and IEC compliance for the SENTRON 5SL series.
