Industrial motor control in harsh environments requires a drive that withstands dust, moisture and temperature extremes. Siemens SINAMICS G115D is an IP65/66 wall-mounted frequency converter designed for SIMATIC control systems, delivering 4kW at 380-480V with 20.4A output. Output frequency ranges 0-550Hz with -30°C to +40°C operating temperature. This replaces cabinet-mounted drives that require additional enclosure protection.

What motor size can the 6SL3520-2XH04-0AB0 drive?

The 4kW rated power at 380-480V with 20.4A output is suitable for medium-to-large industrial motors up to 4kW – typically found in large conveyors, fans, pumps and compressors. The 0-550Hz output frequency range provides wide speed control capability. This replaces fixed-speed motor starters that cannot provide variable speed control.

Why choose IP65/66 protection for a frequency converter?

Cabinet-mounted drives require additional enclosures for outdoor or washdown environments – adding cost and space. The SINAMICS G115D series offers IP65/66 / UL Type 4X protection directly on the drive, suitable for dusty, wet or outdoor installations. Operating temperature range of -30°C to +40°C covers most industrial environments. This replaces drives that require separate NEMA enclosures for harsh environments.
