Product details

Fit and integration

The 5SY6380-7CC occupies 3 modular width units (54 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. It mounts in any position and uses a quick assembly system for snap-on rail fitting. The IP20 rating (with connected conductors) means it is intended for enclosed panel use, not washdown or outdoor exposure. The combined terminal top and bottom accept supply from either end, and the sealable design allows panel-lock tagging for tamper-evident installations.

Electrical ratings and environment

Rated operating voltage is 400 V AC (multi-phase) and 440 V AC single-phase, with a frequency range of 50/60 Hz. The DC rated maximum is 72 V. The pollution degree is 3 (conductive or dry non-conductive pollution), and the overvoltage category is III (fixed installation distribution level). Ambient temperature range is -40 °C to 75 °C, with humidity limits of 95% at 55 °C derating to 35% at 75 °C. Vibration resistance per IEC 60068-2-6 is ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz. Power loss per pole at rated current in hot state is 5.6 W.
