Power module with dual overload curves and integrated braking chopper
The Siemens 6SL3211-1PE27-5UL0 is a SINAMICS G120 PM240-2 Push Through power module rated for 3AC 380-480 V +10/-20 %, 47-63 Hz. It delivers 30 kW under high overload (HO) conditions — 200 % for 3 s, 150 % for 57 s, 100 % for 240 s at ambient -20 to +50 °C — and 37 kW under low overload (LO) at 150 % for 3 s, 110 % for 57 s, 100 % for 240 s at -20 to +40 °C. The built-in braking chopper handles vertical loads or short deceleration profiles without an external resistor module.
What the overload ratings mean for your application
The HO curve (30 kW) is the rating that governs real motor starting and cyclic loading: 200 % torque for 3 seconds covers breakaway on a loaded conveyor or pump, and the 57-second 150 % window handles acceleration. The LO curve (37 kW) applies to steady-state fan or compressor duty where peak demand stays under 110 %. The 240-second thermal recovery period at 100 % means the module resets for the next cycle within four minutes — critical for sequencing multiple starts on a single drive.
Panel integration and mechanical fit
The FSD frame size measures 517 x 275 x 237 mm (H x W x D) with IP20 protection — suitable for enclosure mounting where the push-through design lets the heatsink protrude through the panel cutout, saving interior depth. No Control Unit is included; the module accepts a CU via the front slot, approved for firmware V4.7 SP6.
