That 10 kA at 400 V AC means it can safely interrupt a fault current up to 10 000 A without welding its contacts or cascading the fault upstream — a standard residential and light-commercial panel rating. The B-curve (3–5× In magnetic trip) is the go-to for general-purpose resistive and lighting loads where inrush is low; it keeps nuisance trips off the board compared to a C-curve on motor or transformer circuits. This part occupies 2 modular width units (36 mm wide). Mounting position is any. ## Panel integration and accessories The 5SL4216-6 accepts supplementary devices (auxiliary switches, shunt trips, alarm contacts) via the product extension slot on the right side — useful for remote status or emergency-off circuits without adding a separate relay. Sealable terminals are standard, so a panel builder can lock the cover after commissioning to prevent tampering. Halogen-free and silicon-free construction matters if the board goes into a cleanroom or a corrosive environment where outgassing is a concern. Installation depth is 70 mm. Power loss per pole at rated current in hot operating state is 1.8 W.","metaTitle":"Siemens 5SL4216-6 SENTRON MCB, 2P B 16A 10kA","metaDescription":"Siemens SENTRON 5SL4216-6 miniature circuit breaker, 2-pole, B-curve, 16 A, 10 kA breaking capacity per EN 60898.
