Siemens 6SL3210-1PE21-1UL0 SINAMICS PM240-2 3AC 400V 4kW IP20 Power Module

The Siemens 6SL3210-1PE21-1UL0 is a SINAMICS PM240-2 power module rated 4 kW low-overload / 3 kW high-overload at 3 AC 380-480 V input, with a built-in braking chopper and IP20 protection in frame size FSB. It supplies output current up to 15.4 A and is ordered without a control unit or operator panel.

Technical Specifications

Selection Notes

The 4 kW/3 kW LO/HO split follows Siemens' dual-rating convention: use the 4 kW low-overload figure for continuous, steady loads such as pumps and fans, and the 3 kW high-overload figure when the application needs 200% torque for 3 s starting transients such as conveyors or positioning axes. The built-in braking chopper removes the need for a separate braking module wherever the drive needs dynamic braking, such as vertical axes or fast decelerations. Frame size FSB and IP20 protection mean it is a power stage for cabinet mounting only - a G120 control unit is still required to run it.

Applications

Used in modular SINAMICS G120 drive assemblies for pumps, fans, conveyors, and mixers in the 3-5 kW range where the built-in braking chopper handles occasional dynamic braking.
