At 5.5 kW (13.2 A rated, 26.4 A overload), the 6SL3520-0XA25-5AA0 is the mid-power anchor of the FSC frame. The 425 × 180 × 169 mm enclosure with IP66 protection withstands high-pressure washdown on food-and-beverage conveyors — the integrated fan delivers active cooling at 540–580 mA 24 V DC draw without sacrificing the sealed enclosure rating.

How does the FSC frame handle thermal management at 5.5 kW?

The FSC frame introduces forced-air cooling via an integrated fan, keeping the 5.5 kW power stage within its 170.9 W power-loss budget across a −30 to +40 °C ambient range. The 88 Ω integrated braking resistor with 20 W continuous / 200 W peak capacity handles regenerative energy from frequent conveyor starts and stops without an external brake chopper. Power conductors at this rating typically use 4–6 mm² cross-section — the gland entry accepts these directly through the enclosure wall with a compression seal rated for the full IP66 envelope.

Key specifications

The drive operates from a 3 AC 380–480 V supply (45–66 Hz) with an output frequency range of 0–550 Hz. High-overload capability delivers 200% for 3 seconds and 150% for 57 seconds. Communication is via the integrated AS-Interface fieldbus. The built-in C2 RFI filter meets EN 61800-3 Category C2 conducted emission limits for industrial environments.
