At 440 VAC in single- or multi-phase operation, the same 6 kA rating holds, so it covers 400/440 V panels without derating. The 2-pole design switches both phase conductors but leaves the neutral unswitched — typical for single-phase branch circuits in European-style distribution boards. Rated for 50/60 Hz AC supply only, with a maximum DC operating voltage of 72 V — not a DC-rated breaker for solar or battery strings. ## Panel fit and environmental range The 2 MW (modular width) footprint matches standard DIN-rail enclosures — no special adapters needed. Ambient temperature range spans -40 °C to 75 °C, with humidity derating: 95% RH up to 55 °C, 55% RH up to 70 °C, and 35% RH at 75 °C. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz — enough for machine-mounted panels on pumps or conveyors.","metaTitle":"Siemens 5SY6204-6CC SENTRON MCB, B-Curve 2-Pole, 6 kA","metaDescription":"Siemens SENTRON 5SY6204-6CC miniature circuit breaker, B-curve, 2-pole, 6 kA per EN 60898 at 400 VAC.
