OEM Carrier Transformer 460V Primary / 230V Secondary 1564VA for Model PY3GEAA60090NA

This is the genuine OEM replacement transformer (part number HT01BC701) factory-specified for the Carrier PY3GEAA60090NA rooftop/packaged unit. The transformer steps the unit's 460V primary supply voltage down to a 230V secondary output at a robust 1564VA capacity, delivering reliable power to downstream controls, motors, and auxiliary circuits. When this transformer fails, you'll typically see a completely unresponsive unit — no thermostat response, no contactor pull-in, and no blower operation — because the downstream control voltage is lost entirely.

• Specs: 460V Primary | 230V Secondary | 1564 VA Rating | OEM Part Number HT01BC701 | Also referenced as BE33426001
• OEM vs Generic: This is a genuine Factory Authorized Parts transformer wound and tested to Carrier's exact VA rating and insulation class. Off-brand substitutes often carry lower VA ratings and looser voltage tolerances, risking premature failure and nuisance tripping on commercial equipment.
• Install difficulty: 3/5 — Commercial 460V work requires licensed technicians in most jurisdictions. De-energize and lock out/tag out the unit before any work. Tools needed: multimeter, insulated screwdrivers, wire nuts or ring terminals, and a clamp meter to verify output voltage post-install. Always photograph existing wiring before disconnecting.
• Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.

Compatibility: Engineered and factory-matched for Carrier model PY3GEAA60090NA packaged/rooftop units.
