Siemens 6SL3210-1PE21-4UL0 SINAMICS G120 PM240-2 5.5kW 400V IP20 VFD Power Module

The Siemens 6SL3210-1PE21-4UL0 is a SINAMICS G120 PM240-2 power module rated 5.5kW low overload (LO) / 4.0kW high overload (HO) at 380-480V 3AC, IP20, with a built-in braking chopper and no line filter fitted. It requires a separate SINAMICS control unit to run, ships without a control unit or operator panel, and supports control unit firmware version V4.6.

Technical Specifications

Selection Notes

The built-in braking chopper means no separate braking module is needed for dynamic braking within its capacity, which matters for overhauling loads or fast decel cycles. The HO rating (4.0kW, 200% overload for 3s) suits constant-torque loads such as conveyors that need high starting torque, while the LO rating (5.5kW, 150% overload for 3s) suits variable-torque loads like pumps and fans that run mostly at steady speed. This module ships without a line filter, so an external EMC filter is required where conducted-emission limits apply, and it needs a separate SINAMICS control unit since the power module itself has no onboard control electronics or operator interface.

Applications

Motor control for pumps, fans and conveyors in the 4-5.5kW range on modular SINAMICS G120 drive systems where a built-in braking chopper is needed without an EMC filter fitted at the power module.
