The Siemens SENTRON 5SL6463-6CC is a 4-pole miniature circuit breaker (MCB) with a B tripping characteristic, rated at 63 A and 400 V AC, with a 6 kA breaking capacity per EN 60898.
B-curve trip and thermal derating
The B characteristic (3–5× In instantaneous trip) suits circuits with low inrush — lighting, resistive loads, or control transformers. At a 40 °C ambient the continuous rating derates to 60.17 A, and at 55 °C to 55.66 A; factor this into panel thermal calculations if the breaker shares an enclosure with other heat sources.
Integration notes
Sealable, halogen-free, and silicon-free construction suits clean-room or food-beverage panel environments.
