It carries a 6 kA breaking capacity per EN 60898 at 400 V AC, making it suitable for residential and infrastructure branch-circuit protection where moderate fault levels are expected. ## B-curve and breaking capacity The B-curve (tripping characteristic class B) means the magnetic trip operates at 3 to 5 times rated current — 30 to 50 A for this 10 A unit — so it is a good fit for resistive and general-purpose loads where inrush is modest. The 6 kA breaking capacity at 400 V AC (per EN 60898) tells you it can safely interrupt a fault up to that level without upstream damage; the standard certifies it for overcurrent protection in final circuits. Rated voltage for single-phase operation is 250 V AC; multi-phase (line-to-line) goes up to 440 V AC. The DC rating maxes at 72 V, so this is primarily an AC device. The 5SL6210-6MB snaps onto a standard DIN rail (mounting position any) and occupies 2 modular width units (36 mm total). Depth is 76 mm, height 90 mm, installation depth 70 mm — verify clearance to the enclosure door or gland plate. Sealable, halogen-free, silicon-free — these matter for compliance in clean-room or sensitive environments. Touch protection is built in.","metaTitle":"Siemens 5SL6210-6MB SENTRON MCB, 2P B 10A, 6kA","metaDescription":"Siemens 5SL6210-6MB SENTRON miniature circuit breaker, 2-pole, B-curve, 10 A rated, 6 kA breaking capacity per EN 60898 at 400 V AC.
