The XTRTRA0047 is the dual-primary member of our 150 VA control transformer range: the primary accepts either 460 or 480 VAC, and the secondary delivers 240 VAC for the controller's control circuit. Drawing identification: XTR9.
That dual 460/480 VAC input is what sets this unit apart from single-voltage 460 V transformers — if your service measures 480 VAC, this is the part your panel needs. Replace the transformer when the 240 V control side is dead with a live primary, when the windings show heat damage, or when the unit buzzes and overheats under normal load.
