Power module for pump and fan duty in washdown environments
The Siemens 6SL3223-0DE25-5BA0 is a SINAMICS G120P Power Module PM230 with an integrated Class B EMC filter and an IP55/UL Type 12 enclosure, rated for 380-480 V 3 AC at 47-63 Hz. It delivers 5.5 kW under low overload (150% for 3 s, 110% for 57 s, 100% for 240 s) at 0 to +40 °C ambient. This module is designed to be paired with a CU230P-2 Control Unit running firmware V4.3.2 or higher — the control unit is ordered separately. The IP55 rating means the enclosure withstands hose-directed water and dust ingress, making this module suited for food-and-beverage processing lines, wastewater treatment, and other wet-area installations where a standard IP20 drive would require a separate cabinet. The integrated Class B filter meets conducted emission limits for residential and light industrial environments without an external filter.
What the low-overload rating means for the load
The 5.5 kW low-overload rating defines the continuous motor power the module can deliver while still providing 150% current for 3 seconds during startup or load transients. This suits variable-torque loads like centrifugal pumps and fans where peak demand is brief. For constant-torque loads (conveyors, positive-displacement pumps), the high-overload curve would govern — but this module's spec sheet lists only the low-overload characteristic, so match it to loads that do not require sustained high starting torque.
