That 10 kA figure is the maximum prospective fault current it can safely interrupt — enough for most residential and light commercial distribution boards where the upstream transformer impedance keeps the short-circuit level below that threshold. The C-curve (magnetic trip between 5 and 10 times In) means it tolerates moderate inrush without nuisance tripping, so it suits mixed loads with some motor or capacitive start-up current. It occupies a single modular width unit (18 mm) on standard DIN rail, with a depth of 76 mm and an installation depth of 70 mm. The IP20 rating (with connected conductors) is typical for enclosed distribution boards — no special sealing needed inside the panel. ## Integration notes Mounts in any position on a standard DIN rail. The sealable design allows the installer to lock the toggle position after commissioning — useful for tamper-proofing in shared-access panels. Halogen-free and silicon-free construction reduces corrosive off-gassing risk in enclosed spaces. Supplementary devices (auxiliary switches, shunt trips, undervoltage releases) can be added on the right side via the product extension feature. ## Environmental range Rated for ambient temperatures from -40 °C to +75 °C, which covers unheated enclosures in cold climates and hot switchrooms. The power loss per pole at rated current in hot state is 0.86 W — negligible for thermal budgeting in a populated board. Mechanical service life is 10 000 operating cycles typical.","metaTitle":"Siemens 5SL4306-7RC SENTRON MCB, 3P C 6A 10kA 415V","metaDescription":"Siemens SENTRON 5SL4306-7RC miniature circuit breaker, 3-pole, C-curve, 6 A, 10 kA breaking capacity per EN 60898 at 415 V AC.
