Siemens 6SL3210-1PE31-1UL0 SINAMICS G120 PM240-2 3AC 400V 55kW/45kW VFD Power Module

The Siemens 6SL3210-1PE31-1UL0 is a SINAMICS G120 PM240-2 power module rated 55 kW low overload / 45 kW high overload at 3AC 380-480V, supplied in an IP20 frame size FSE without a filter but with a built-in braking chopper. It delivers up to 180 A maximum output current at a 4 kHz pulse frequency and requires a separate PM240-2 control unit to operate.

Technical Specifications

Selection Notes

This PM240-2 has an integrated braking chopper but no line filter - add an external EMC filter if the installation needs conducted-emission compliance, since the filtered PM240-2 variants in the same frame carry one built in. Rate the load against the low-overload figures (55 kW / 104 A) for continuous variable-torque duty such as pumps and fans, and against the high-overload figures (45 kW / 94 A) for constant-torque duty like conveyors and extruders that need 150% for 57 s. This power module needs a matching PM240-2 control unit - it has no onboard I/O or fieldbus interface of its own.

Applications

Used as the power stage of a modular SINAMICS G120 drive for pump, fan, and conveyor applications at 380-480 V, where the built-in braking chopper handles regenerative energy from decelerating loads without a separate braking module.
