The Siemens 6SL3225-0BH33-7UA1 is a SINAMICS G120 PM260 Power Module — the power stage for a modular drive system. It's unfiltered and capable of energy recovery, meaning it can feed regenerative energy from a decelerating motor back into the line, which cuts braking resistor losses on applications like conveyors, centrifuges, or winders.
Overload capability and ambient limits
Rated for 500-690 V 3 AC ±10%, 47-63 Hz. Two duty ratings: high overload (HO) delivers 37 kW with 200% overload for 3 s, 150% for 57 s, 100% continuous at -10 to +50 °C ambient. Low overload (LO) delivers 55 kW with 140% for 3 s, 110% for 57 s, 100% continuous at -10 to +40 °C. That 200% HO spike is what you need for starting high-inertia loads or clearing a jam without tripping.
