Power module for a specific duty cycle
The Siemens 6SL3224-0BE24-0UA0 is a SINAMICS G120 PM240 Power Module, listed as a spare part. It's an unfiltered unit with an integrated braking chopper, designed for 380-480 V 3 AC input at 47-63 Hz. The key spec is the high overload rating: 4.0 kW at 200% for 3 seconds, 150% for 57 seconds, and 100% for 240 seconds. That means it can handle short bursts of heavy load — think a crusher or a centrifuge that needs a kick to start — without tripping, but it's not sized for continuous overload. The ambient temperature range is -10 to +50 °C, and it's IP20 so it belongs in a clean, dry enclosure, not on the plant floor.
The 200% overload for 3 seconds is the number that governs the real-world application. A standard 4 kW drive might handle 150% for 60 seconds; this one gives you a 200% punch for a very short window. That's sized for starting a loaded conveyor or a high-inertia fan, not for a pump that draws steady current. The 150% for 57 seconds covers the acceleration ramp. The unfiltered design means you'll need an external line reactor or filter if the installation has strict harmonic limits. The integrated braking chopper saves an external resistor for deceleration — useful for vertical loads or fast stops. The FSB frame size (270 x 153 x 165 mm) determines the mounting footprint and the DIN-rail or screw-panel integration.
