Where the incoming service runs at 480 or 460 VAC, the XTRTRA0124 handles the low-voltage side: this 25 VA control transformer drops a 480/460 VAC primary to a 24 VAC secondary. Drawing identification: XTR1.

It is the high-voltage counterpart to the 208 V XTRTRA0121 — same 25 VA rating, different primary — so check the supply voltage on your panel nameplate before ordering. Because 25 VA covers only modest control loads, also make sure your schematic does not call for one of the 100 VA transformers instead. Verify the primary wiring against the measured line voltage before energizing a new unit.

A correct-fit replacement for pump controller control circuits on 480/460 VAC service. Cybertronic Controls is veteran-owned and based in Hammond, Louisiana; call 985-351-5681 and we will confirm the XTRTRA0124 against your panel drawing before it ships.
