The Siemens 6SL3200-6AM14-1AH0 is a Filter type A for the G120P drive family, rated for 1.5 kW power output and 4.1 A output current at 400 V operating voltage. It is designed for 50/60 Hz line frequencies and carries EN 61800-3 compliance, which covers EMC emission and immunity for adjustable-speed drive systems — meaning it is intended for installation in a drive cabinet where conducted and radiated noise from the inverter stage is suppressed to meet the standard's limits.
Overload and protection profile
The filter supports the drive's overload capacity: 110 % for 57 seconds and 150 % for 3 seconds every 300 seconds. This matches the typical G120P overload curve for fan and pump loads — the 57-second window at 110 % handles a blocked-rotor start or a momentary load spike without tripping, while the 3-second 150 % peak clears a short-duration surge. The IP55 degree of protection means the enclosure is dust-protected and can withstand water jets from any direction, so it can be mounted in a washdown area or outdoors under a roof.
Communication and fieldbus
The filter itself is a passive component, but the G120P drive it mates with supports Modbus/RTU, RS485/USS, BACnet MS/TP, and optional PROFIBUS, PROFINET, and CANopen. No fieldbus wiring runs through the filter — it sits on the line side between the mains and the drive's rectifier.
