It snaps onto a DIN rail and occupies 2 modular width units (36 mm), making it a standard fit for residential and light-commercial distribution boards where the B curve protects lighting and general-purpose socket circuits against short-circuit and overload. ## Key ratings and what they mean for fit The 16 A rating at 30 °C sets the continuous load it can carry without tripping — sized for a branch circuit feeding receptacles or fixed lighting. The B characteristic means it trips at 3 to 5 times rated current (instantaneous), so it's the right choice for resistive and lightly inductive loads where inrush stays modest; avoid it on motor or transformer primaries where a C or D curve would be needed to ride through the start surge. Breaking capacity of 7.5 kA per EN 60898 tells you the maximum fault current this MCB can safely interrupt. In a residential or small commercial panel with a typical upstream transformer impedance, that's usually adequate — but if the prospective short-circuit current at the board exceeds 7.5 kA, you need a higher-rated unit or a current-limiting upstream device. Rated for 415 V AC and 250 V single-phase, with a maximum of 440 V in multi-phase operation. The 50/60 Hz frequency range covers standard mains worldwide. IP20 with connected conductors is the usual finger-safe protection for a panel interior — no washdown rating, so keep it inside the enclosure. Mechanical life of 10,000 operating cycles is typical for this class — fine for normal switching duty, but if you're cycling it daily as a disconnect under load, expect to replace it sooner. Power loss of 1.9 W per pole at rated current matters for thermal budgeting inside a densely packed enclosure; multiply by two poles for total dissipation. ## Panel integration notes Mounts in any position on a 35 mm DIN rail. Depth of 76 mm and installation depth of 70 mm leave clearance for wiring behind the rail. The 36 mm width — 2 MW — means it takes two adjacent 18 mm slots in a distribution board. Sealable for tamper-proofing after commissioning. Halogen-free and silicon-free construction avoids corrosive off-gassing in sealed enclosures. Supplementary devices (auxiliary contacts, shunt trips, undervoltage releases) can be added on the right side without increasing the pole count — useful for remote tripping or status feedback. Overvoltage category III and pollution degree 2 are standard for fixed-installation distribution boards.","metaTitle":"Siemens 5SL6216-6RC SENTRON MCB, 16A, 2-Pole, B Curve, 7.5kA","metaDescription":"Siemens 5SL6216-6RC SENTRON miniature circuit breaker, 16A rated, 2-pole, B tripping characteristic, 7.5 kA breaking capacity per EN 60898.

The 5SL6216-6RC is a 2-pole, 16 A, B-curve unit at 7.5 kA, fitting 2 MW (36 mm). They are not drop-in replacements: the pole count, current rating, and tripping characteristic differ. The 5SL4363-7 also carries an IEC 60947-2 rating of 10 kA, while the 5SL6216-6RC is rated per EN 60898 at 7.5 kA."},{"question":"Will 5SL6216-6RC drop into a panel that was specified around 5SL4363-7 without rewiring?","answer":"No. The 5SL6216-6RC is a 2-pole unit (36 mm wide) while the 5SL4363-7 is a 3-pole unit (54 mm wide). The pole count, current rating (16 A vs 63 A), and tripping characteristic (B vs C) are all different. The panel would need rewiring and possibly a different busbar arrangement."},{"question":"What compliance documentation does Siemens provide for 5SL6216-6RC?","answer":"The 5SL6216-6RC is certified per EN 60898-1 for breaking capacity. It is halogen-free and silicon-free. Standard Siemens documentation includes a CE declaration of conformity and a datasheet with IEC ratings.
