OEM Carrier Step-Down Transformer 460V/230V 1564VA for Model PY3GEAA48130AA

This genuine OEM Carrier transformer (part number HT01BC701) is the factory-specified replacement for the Carrier PY3GEAA48130AA packaged rooftop unit. This heavy-duty step-down transformer reduces the incoming 460V primary supply voltage to a 230V secondary output at a robust 1564VA capacity, powering critical internal components and control circuits within the unit. When this transformer fails, the result is typically a complete loss of control power — the unit will not respond to thermostat calls, contactors will not energize, and the system will appear entirely dead.

• Specs: 460V Primary | 230V Secondary | 1564VA Capacity | OEM Part: HT01BC701 | Compatible Cross: BE33426001
• OEM vs Generic: This is a Factory Authorized Parts (FAP) OEM transformer wound and insulated to exact Carrier specifications. Aftermarket transformers of this VA rating frequently fall short on insulation class and voltage regulation, risking secondary component damage in commercial RTU applications.
• Install Difficulty: 3/5 — Commercial 460V circuits require a licensed electrician in most jurisdictions. Always de-energize and lock out/tag out (LOTO) the unit before servicing. Tools needed: insulated screwdrivers, multimeter, wire nuts or terminal connectors, and a clamp meter to verify output voltage post-installation.
• Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse.
