Product details

Siemens 5SY6313-8 SENTRON MCB — 13 A, D-Curve, 3-Pole

It is designed for 400 V AC systems and carries a breaking capacity of 6 kA per EN 60898 and 15 kA per IEC 60947-2, with a 5 kA interrupting rating under UL 1077 / CSA C22.2 No.235. The 15 kA breaking capacity under IEC 60947-2 gives headroom for industrial panels with higher available fault current than a standard 6 kA residential-grade MCB would handle.

Occupies 3 width units (54 mm). Mounting position any. Sealable, touch-protected per IP20 with connected conductors.

Halogen-free and silicon-free construction. Humidity tolerance: max 95% at 55 °C, derating to 35% at 75 °C. Overvoltage category III. Suitable for mechanical engineering and industry applications per the manufacturer's designation.
