Product details

Siemens SENTRON 5SL6363-6CC — 3-pole B-curve MCB, 63 A, 6 kA

Rated current derates with ambient temperature: 63 A at 30 °C, 60.17 A at 40 °C, 58.71 A at 45 °C, and 55.66 A at 55 °C. If the panel runs warm — typical in a crowded enclosure — factor the 40 °C figure (60.17 A) as the practical continuous rating.

Mounting position is unrestricted — installs vertically, horizontally, or inverted without derating.
