The C-curve (tripping characteristic class C) means the MCB holds through 5–10× rated current for short-duration inrush — typical for motor-starter and transformer loads where the magnetic trip must not nuisance-trip on startup. The 6 kA rating per EN 60898 is the maximum prospective fault current it can safely interrupt at 400 V AC; for UL 1077 and CSA C22.2 No. 235 installations the rating drops to 5 kA. That 1 kA gap matters if you are specifying for a North American panel with a higher available fault current — you need the IEC rating or a higher-interrupting device. The 3.8 W power loss per pole at rated current in hot operating state adds up to 7.6 W for the 2-pole unit; account for that in enclosure thermal calculations, especially in a crowded DIN rail. ## Integration — what fits and what does not The 5SY6250-7CC occupies 2 modular-width units (36 mm wide) and installs in 70 mm depth behind the panel surface (overall depth 76 mm including the front projection). It does not switch the neutral conductor (2-pole design with no neutral switching). The vibration resistance per IEC 60068-2-6 is ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz — adequate for most industrial panels but verify against your specific machine's resonance spectrum if the breaker is mounted on a vibrating sub-panel.","metaTitle":"Siemens 5SY6250-7CC SENTRON MCB, C-Curve, 2-Pole, 6 kA","metaDescription":"Siemens 5SY6250-7CC SENTRON miniature circuit breaker, C-curve, 2-pole, 6 kA per EN 60898, 400 V AC.
