Power Module for SINAMICS G120 — PM230 with Integrated Filter
The Siemens 6SL3211-1NE21-8AG1 is a SINAMICS G120 PM230 Power Module in frame size FSB, rated for 380-480 V AC three-phase input at 47-63 Hz. It delivers 7.5 kW under low overload conditions: 150% rated current for 3 seconds, 110% for 57 seconds, and 100% for 240 seconds, within a 0 to +40 °C ambient. The module includes an integrated Class A EMC filter and carries IP20 degree of protection, making it suitable for installation inside a standard control cabinet with filtered airflow.
Deployment Context
The PM230 is designed for variable-torque applications such as pumps and fans in building services and industrial processes. Its IP20 enclosure and 345 x 154 x 171 mm (HxWxD) footprint fit a standard 400 mm deep cabinet on a mounting plate. The integrated Class A filter meets EN 61800-3 for first environment (residential) conducted emissions, so no external filter is needed for most installations — but check your local grid code if the drive feeds a TN or IT system.
Overload Profile and Sizing Note
The low-overload rating of 7.5 kW at 150% for 3 seconds defines the motor sizing boundary: a 7.5 kW pump or fan starting against a closed valve will stay within the thermal limit. The 110% for 57 seconds covers acceleration to full speed. If your load requires higher breakaway torque or a longer ramp, step up to the next frame size — the PM230's overload capacity is not adjustable above the stated curves.
