The Siemens 5SL4506-7 is a SENTRON miniature circuit breaker rated 6 A with a C-curve tripping characteristic, 1P+N pole configuration, and a 10 kA breaking capacity per both EN 60898 and IEC 60947-2.
The 90 mm height and 36 mm width are standard for a 1P+N MCB in a DIN-rail enclosure — no surprises for the panel builder laying out the gland plate. Mounting position is unrestricted; the breaker can be oriented any way the cabinet layout demands. IP20 protection with connected conductors — standard for a distribution board interior.
Breaking capacity is 10 kA under both EN 60898 (household and similar installations) and IEC 60947-2 (industrial switchgear). That dual-rated 10 kA figure is the same for both standards — no derating needed when moving from a residential to a light-industrial application, as long as the prospective fault current stays at or below 10 kA. Power loss is 1.6 W per pole in hot operating state at rated current. For a 1P+N breaker that means 1.6 W total dissipation — negligible for thermal budgeting inside a distribution board, but worth noting if you are packing many breakers into a small enclosure with limited ventilation. DC rated maximum is 72 V — usable on DC control circuits at that voltage, but the 10 kA breaking capacity applies to AC only; DC interrupting performance is not specified here.
Pollution degree 2 (non-conductive pollution with occasional condensation) and overvoltage category III (equipment in fixed installations with high transient overvoltages) — standard for distribution boards downstream of the utility meter.
