What this filter does on the line
The Siemens 6SL3200-6AE15-8AH0 is a Filter A line filter for the G120P variable speed drive family, frame size FSA. It's sized for a 2.2 kW drive output at 400 V, carrying 5.9 A continuous. The filter attenuates conducted emissions to meet EN 61800-3, which is the EMC standard for adjustable-speed power drive systems — meaning it keeps the drive's switching noise off the plant power bus so it doesn't trip upstream RCDs or interfere with nearby instrumentation. Rated for 50/60 Hz line frequencies, so it works on either 50 Hz or 60 Hz mains without derating.
