Siemens 14DUA32WH Motor Starter
14DUA32WH — FVNR Size 1 Starter, 0.25–1 A
The 14DUA prefix identifies a Siemens Class 14FVNR (Full-Voltage Non-Reversing) Size 1 across-the-line motor starter. The suffix WH denotes a NEMA 4X (fiberglass) enclosure.

Chassis-mount construction requires panel installation; NEMA 4X rating suits indoor wet or mildly corrosive environments. The 0.25–1 A range covers Size 1 fractional motors; output rating of 27 A reflects the starter's internal contact capacity rather than the adjustable overload setting.
Package Variants Across the Family
The eight alternates share identical electrical and thermal specifications. Two packaging distinctions exist:
- Box: 14DUA32WH, 14DUA32WG, 14DUA32WJ, 14DUA32WF, 14DUA32WA
- Bulk: 14DUA32WC, 14DUA32WE, 14DUA32WD
Suffix WH in the seed designation specifically flags the NEMA 4X fiberglass enclosure variant; bulk-packaged versions typically serve OEM panel assemblies where enclosure is supplied separately.
Key Confirmation Points
- Verify the overload heater range matches the connected motor nameplate full-load amperes
- Confirm chassis dimensions are compatible with the intended mounting enclosure or subpanel
- NEMA 4X (fiberglass) suits the installation environment; stainless steel suffixes (WC, WE) imply different corrosion ratings
