What the ratings mean for fit
The 5SL4610-8 is a 4-pole (3P+N) miniature circuit breaker from the SENTRON family, with a D tripping characteristic rated 10 A at 30 °C. The D curve means it tolerates high inrush currents — typical for motor, transformer, or lighting ballast loads — without nuisance tripping. Breaking capacity is 10 kA per both EN 60898 and IEC 60947-2, so it safely clears faults up to that level in residential or light commercial infrastructure panels. The 400 V AC supply rating and 440 V AC multi-phase maximum match standard three-phase distribution. Thermal derating is published: 9.24 A at 40 °C, 8.8 A at 45 °C, and 7.96 A at 55 °C. If the panel ambient runs hot, size the load accordingly — the 10 A nameplate is only valid at 30 °C. The breaker is IP20 with connected conductors, so it's intended for enclosed distribution boards, not wet or dusty environments.
Panel integration notes
Snap-on DIN rail mount, any position. Occupies 4 modular width units (72 mm wide, 90 mm tall, 76 mm deep, 70 mm installation depth). The sealable housing is halogen-free and silicon-free, which matters for panels in environments sensitive to outgassing — food processing, medical, or telecom shelters. Touch protection is built in.
Compliance and documentation
Rated for overvoltage category III, pollution degree 2, energy limitation class 3. The neutral conductor is switched (3P+N). Mechanical service life is 10 000 operating cycles typical. The part carries IEC and EN markings for the listed breaking capacities; compliance documentation (RoHS, REACH, UL, IEC) is provided by Siemens with the product.
