As a genuine Factory Authorized Part, this transformer acts as the \"electrical heart\" of your HVAC equipment, converting high-voltage incoming power (120V, 208V, or 240V) into the stable 24V Alternating Current required to operate the thermostat, control board, and safety switches. It is specifically designed to handle the inductive loads of contactors and relays, ensuring that the system's \"brain\" receives constant, filtered power to manage heating and cooling cycles without the risk of voltage fluctuations or brownouts.\u003c\/p\u003e\n\u003ch2\u003eKey Features:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine OEM Precision:\u003c\/strong\u003e Engineered under part number \u003cstrong\u003eHT01CN241\u003c\/strong\u003e to meet the exact secondary voltage output and VA rating required by Carrier Corporation’s sensitive electronic control boards.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Tap Primary Versatility:\u003c\/strong\u003e Features multiple primary lead wires (Black, White, Red, Orange) allowing for seamless installation in 120V, 208V, or 240V applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRobust 40VA Power Rating:\u003c\/strong\u003e Provides a strong 40 Volt-Amp capacity, ensuring ample power for modern \"smart\" thermostats and multiple-stage cooling contactors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass 2 Energy Limiting:\u003c\/strong\u003e Built with internal thermal protection to prevent overheating and circuit damage in the event of a low-voltage short or system overload.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect-Fit Footprint:\u003c\/strong\u003e Designed with the standard OEM mounting bracket and color-coded lead wires for a fast, \"drop-in\" replacement that maintains factory safety standards.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eProduct Details:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Factory Authorized Parts™ (Carrier\/Bryant\/Payne)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e United Technologies \/ Carrier Corp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e HT01CN241\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.1 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Voltage:\u003c\/strong\u003e 120V \/ 208V \/ 240V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Voltage:\u003c\/strong\u003e 24V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Rating:\u003c\/strong\u003e 40VA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type:\u003c\/strong\u003e Color-Coded Lead Wires\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e🛠️ HVAC Depot Pro Tip: Practical Installation Advice\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003e\"Check for the Short First!\"\u003c\/strong\u003e Transformers like the HT01CN241 rarely fail on their own; they usually \"burn out\" because of a short circuit in the 24V wiring (like a rubbed-out wire at the outdoor condenser). Before installing the new unit, \u003cstrong\u003etake a picture\u003c\/strong\u003e of the original wiring. Once installed, we highly recommend adding a \u003cstrong\u003e3-amp or 5-amp automotive-style fuse\u003c\/strong\u003e in-line on the secondary (R) wire. This ensures that if the short still exists, you only blow a cheap fuse instead of destroying your brand-new OEM transformer.\u003c\/p\u003e\n\u003ch2\u003eCross-Reference:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperseded Numbers:\u003c\/strong\u003e HT01CN238, HT01CN235, HT01CN239\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLegacy Numbers:\u003c\/strong\u003e 1173516, 1171746\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrawing Numbers:\u003c\/strong\u003e 311340-401, P251-2403\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquivalent Brands:\u003c\/strong\u003e Bassler, Jard, White-Rodgers (Carrier Certified Series)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eModel Compatibility:\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003e58STA\/58STX Series\u003c\/strong\u003e (Suffixes: 045, 070, 090, 110, 135, 155)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e310A\/310J Series\u003c\/strong\u003e (Suffixes: 024045, 036070, 048090, 066110, 066135)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e59SC2\/59SC5 Series\u003c\/strong\u003e (Suffixes: 040S14, 060S14, 080S17, 100S21, 120S24)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e48HG\/48PG Series\u003c\/strong\u003e (Suffixes: 014, 016, 020, 024, 028)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFA4B\/FB4B Series\u003c\/strong\u003e (Suffixes: 018000, 024000, 030000, 036000, 042000, 048000, 060000)\u003c\/p\u003e","brand":"Carrier","offers":[{"title":"Default Title","offer_id":52451491414379,"sku":"662442632913","price":156.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/HT01CN241.jpg?v=1772056385","url":"https:\/\/tophvacparts.com\/products\/factory-authorized-parts-ht01cn241-hvac-transformer-120v-208v-240v-to-24v-40va","provider":"HVAC Parts and Equipment Depot Open To Homeowners and Contractors","version":"1.0","type":"link"}
