The Siemens 5SL4613-8 is a SENTRON miniature circuit breaker (MCB) with a D tripping characteristic, four poles configured as 3P+N, and a rated current of 13 A at 30 °C. Breaking capacity is 10 kA per both IEC 60898 and IEC 60947-2, so it clears faults up to that level without upstream coordination issues in a residential or light-industrial distribution board. The 13 A rating derates with ambient temperature: 12.01 A at 40 °C, 11.44 A at 45 °C, and 10.35 A at 55 °C. The neutral conductor is switched (3P+N), which is required in some regional wiring codes to ensure the neutral is disconnected when the breaker is off. Touch protection is built in;
It occupies 4 modular width units (72 mm wide), with a depth of 76 mm and an installation depth of 70 mm. The 90 mm height keeps it within a standard consumer unit or sub-distribution board. Sealable design allows lockout-tagout in industrial or infrastructure panels. Rated for ambient temperatures from -40 °C to 75 °C, with up to 95% humidity at 55 °C. That range covers unheated electrical rooms in cold climates and warm enclosures near process equipment.
