ST3 platform: cast iron, TEFC/IP55, IEEE 841 severe duty, 460V single voltage. These are not general-purpose motors. TC = C-face footed; T = footed only.
Specs per the WEG manufacturer datasheet (2.76A) — the WEG brochure's 2.61A and reseller transcriptions lose. All ST3Q models are 460V only.
Confirming the right replacement
Before we quote, compare these fields on your failed motor's nameplate. If any of them differ, send us a photo of the nameplate and we'll match it exactly rather than guessing:
- Full model number — including any suffix letters
- HP, RPM, and voltage
- Frame size (e.g. 284T) and enclosure (TEFC, ODP, etc.)
- Full-load amps
