Siemens SENTRON 5SY7163-6 — 63 A, 1-Pole B-Curve MCB
Rated for continuous operation at 63 A up to 35 °C ambient; above that, the thermal derating curve applies — at 40 °C the rating drops to 59.16 A, at 50 °C to 55.06 A, and at 60 °C to 50.65 A. The 76 mm depth fits standard 70 mm installation depth enclosures. Touch protection is integrated on the terminals, and the combined top/bottom terminals accept conductors without special tools.
For compliance documentation, the part carries the manufacturer's declaration of conformity to EN 60898 and IEC 60947-2. It is halogen-free and silicon-free, meeting the material restrictions common in RoHS-driven procurement.
Installation & Integration Notes
The 18 mm width (1 MW) minimizes panel fill — a 24-way distribution board can hold 24 of these single-pole units. The 76 mm depth leaves clearance behind the gland plate for wiring.
