Drive selection memo — 5.5 kW pump/fan duty
The Siemens 6SL3200-6AE21-3AH0 is a SINAMICS G120P variable speed drive in frame size FSB, rated for 5.5 kW output at 400 V with a continuous output current of 13.2 A. It carries Filter A for conducted emissions compliance, making it suitable for European EMC environments without an external filter on the line side. The drive is built for pump and fan applications — the overload profile (110 % for 57 s and 150 % for 3 s every 300 s) matches the low-overload, high-run-time duty cycle typical of centrifugal loads, not high-start-torque conveyors or presses.
The drive measures 100 x 292 x 223 mm (W x H x D) and is rated IP20 — intended for enclosure mounting in a clean, dry electrical room or cabinet. It supports Modbus/RTU, RS485/USS, and BACnet MS/TP natively, with optional PROFIBUS, PROFINET, or CANopen via plug-in modules. The 50/60 Hz line frequency rating covers global mains supplies. Compliance marks include CE, UL, EAC, and RCM, so the unit clears regulatory gates for Europe, North America, Eurasia, and Australia/New Zealand.
