Key specifications

What it is and where it's used

The 6SE6420-2UD21-5AA1 is a Siemens drive from the MICROMASTER 420 / 440 range. Typical applications: Conveyors, pumps and fans, general machine drives. The manufacturer no longer sells this part new, which is why it is sourced from surplus stock elsewhere in Europe.

What to check before ordering

• Match the full order number including the last digits, as they define the frame size and hardware version
• Check whether the drive needs a BOP/AOP panel or communication module, which are ordered separately
• Exact rating (kW, voltage class) and whether the drive has an integrated filter
• Frame size, because the footprint decides whether it fits the cabinet

If you are unsure, send us a photo of the label on the existing unit with your request and we will check it against the part number.
