For motor or transformer circuits with higher inrush, a C- or D-curve would be the better call — this part is sized for the panel's lighting and receptacle branches. If your site's prospective short-circuit current exceeds that, you'd step up to a 6 kA or 10 kA rated MCB — but for standard domestic distribution this is the common rating. Rated operational voltage is 400 V AC for multi-phase operation, with a maximum of 440 V. Single-phase rating is 250 V AC. The DC rating tops out at 72 V, so it's not intended for DC sub-distribution above that level. Temperature range is -40 to 75 °C, which covers unconditioned enclosures in most climates. Halogen-free and silicon-free construction means it meets the material restrictions common in green-building specs and certain industrial environments where outgassing during a fault event is a concern. Depth is 76 mm, height 90 mm — verify enclosure depth clearance, especially if a gland plate or busbar cover sits behind the breaker row. Installation depth is 70 mm, slightly less than the overall depth due to the front toggle projection.","metaTitle":"Siemens 5SL3210-6MB SENTRON MCB, 2-pole B-curve 10 A 400 V A","metaDescription":"Siemens 5SL3210-6MB SENTRON miniature circuit breaker, 2-pole, B-curve, 10 A, 400 V AC, 4.5 kA breaking capacity.

It occupies the same 2 MW footprint and shares the same 4.5 kA breaking capacity, so it drops into the same panel without rewiring — just the current rating differs."},{"question":"Will 5SL3210-6MB drop into a panel specified around 5SL3120-6MB without rewiring?","answer":"Yes — same 2-pole, same B-curve, same 36 mm width, same 4.5 kA breaking capacity. The only difference is the 10 A vs 20 A rating. No busbar or DIN-rail modification needed."},{"question":"What compliance documentation does Siemens provide for 5SL3210-6MB?","answer":"The part carries EN 60898 certification for the 4.5 kA breaking capacity. It is halogen-free and silicon-free.
