Unlike small 40VA control-circuit transformers, this is a heavy-duty \u003cstrong\u003e1564VA isolation transformer\u003c\/strong\u003e that steps line voltage from 460V primary down to 230V secondary to power internal load circuits within the RTU. When this transformer fails, you'll see a complete or partial loss of power to downstream components — no fan operation, no compressor engagement, tripped breakers, or a dead unit that won't respond to any thermostat signal.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 460V Primary | 230V Secondary | 1,564 VA rating | OEM Part No. HT01BC701 | Manufactured by Basler Electric for Carrier Factory Authorized Parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part — not an aftermarket substitute.
