The Siemens SENTRON 5SL4563-6 is a 2-module (36 mm wide) miniature circuit breaker rated 63 A at 230 V AC with a B tripping characteristic and 10 kA breaking capacity per both EN 60898 and IEC 60947-2. The 1P+N configuration switches the line and switches the neutral, making it a direct fit for single-phase final circuits in residential and light commercial distribution boards where neutral isolation is required.
Ratings and what they mean for the panel
The 63 A rating at 230 V AC is the continuous current the breaker carries without tripping under normal conditions — sized for a high-load single-phase circuit such as a large electric water heater or a sub-feed. The B curve (3-5 In instantaneous trip) means it clears short-circuit faults fast but holds through motor inrush on smaller loads; it is the standard choice for residential and general-purpose lighting and socket circuits in Europe. The 10 kA breaking capacity (Icn per EN 60898, Icu per IEC 60947-2) tells you the breaker can safely interrupt a fault current up to 10 000 A without welding its contacts or failing catastrophically — adequate for most domestic and light commercial installations where the prospective short-circuit current at the board is below that level.
Physical fit and wiring
The 36 mm width (2 width units) snaps onto standard DIN rail EN 60715. Terminal capacity accepts solid or stranded copper from 0.75 mm² up to 25 mm², covering most final-circuit cable sizes. Tightening torque for the screw terminals is 2.5 to 3 N·m. The 76 mm depth plus 70 mm installation depth leaves clearance for wiring behind the panel door. IP20 with connected conductors is the expected protection for a DIN-rail device inside a closed enclosure.
