SENTRON 5SY8602-8 — D-curve MCB for high-inrush loads
The Siemens SENTRON 5SY8602-8 is a 4-pole miniature circuit breaker (3P+N) with a D tripping characteristic, rated for 400 V AC at 50/60 Hz. Rated current is 2 A at 45 °C, derated to 1.95 A at 50 °C and 1.9 A at 55 °C — factor this into the thermal coordination if the panel ambient runs warm.
Panel integration and environment
Snap-on DIN-rail mounting, any orientation — the breaker fits standard 35 mm rail. Rated for ambient -40 to 75 °C, with humidity limits: 95% RH up to 55 °C, 55% RH up to 70 °C, 35% RH up to 75 °C. Vibration tested to IEC 60068-2-6 (±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz).
