Questions about this item

What shaft diameter and frame size does the 4UX65 motor need for mounting?

The motor uses a 5/8 in shaft diameter and a 48YZ frame for horizontal mounting.

How do I wire the 115 V AC split-phase motor, and what common mistake should I avoid?

Connect the 115 V AC supply to the split-phase terminals; the frequent error is reversing the CW/CCW rotation leads.

When should I plan to inspect or replace the auto thermal protection on this 1/2 hp motor?

The auto thermal protection resets itself; schedule a check if the motor trips repeatedly under continuous duty at 40 °C ambient.
