The Siemens SENTRON 5SL6202-7RC is a 2 A, 2-pole miniature circuit breaker with a C tripping characteristic, rated to interrupt fault currents up to 7.5 kA per EN 60898 at 415 V AC.
The 2 A rating itself is the continuous load it carries without tripping on thermal overload; the C-curve's magnetic trip band (5–10× In) handles the inrush from a 0.5–1.5 kW motor or a string of LED drivers without nuisance tripping. The DC rating tops out at 72 V, so this is primarily an AC branch-circuit protector — not the part for a DC bus or battery string. Pollution degree 2 covers the typical non-condensing, dry indoor environment of a residential or commercial panel.
The 2 MW (modular width) footprint — 36 mm wide — means it occupies two adjacent 18 mm slots. Mounting position is unrestricted, so it can be installed horizontally or vertically without derating. The sealable design allows the panel builder to lock the toggle position with a lead seal or adhesive label, preventing unauthorized switching in critical circuits. This is useful for remote status monitoring or emergency-off integration in a safety circuit.
The part carries halogen-free and silicon-free construction, which matters for outgassing-sensitive environments like clean rooms or sealed enclosures where corrosive byproducts from a fault event must be minimized. Compliance documentation (RoHS, REACH) is available from the manufacturer on request.
