What Do “K”, “SB”, or “UN SB” Mean?

In many industrial part codes:

• “K” or “SB” typically refers to accessory kits, optional covers, internal boards or communication modules chosen by OEMs.

• “UN SB” may be a vendor-specific code for shipping or packaging type (e.g., unit, segregated boards).
  ABB product codes are mainly power & voltage oriented, not SB vs. UN SB — so those suffixes are usually vendor/packaging tags rather than different electrical versions.
  (Not official ABB designation, often distributor shorthand.)

Conclusion – ABB ACS380

The ABB ACS380 series is a versatile, compact, and highly reliable AC drive for controlling induction and PM motors up to 22 kW, with both 1-phase and 3-phase input options. The model codes (like 040S-02A6-4, 040S-25A0-4, 040S-038A-4) tell you power rating, voltage class, and use case suitability — and suffixes like K or SB are usually internal/packaging or accessory tags, not electrical differences.
