As a critical component of your equipment's control circuitry, this enclosed relay plays a vital role in system safety and performance by safely allowing low-power control signals to switch heavier line-voltage power loads. Maintaining a strong and properly functioning fan relay is essential for preventing blower failures, ensuring seamless heating and cooling cycles, and protecting more expensive system components from electrical damage.\u003c\/p\u003e\n\u003cp\u003eOperating with a 208\/240V coil, this relay features a specialized SPNO\/SPNC (Single Pole Normally Open \/ Single Pole Normally Closed) contact configuration rated for up to 7-8 Amps of inductive load. Opting for a Genuine OEM Trane replacement part matters immensely because it guarantees exact electrical compatibility and a precision fit within your system's existing control panel or bracket. This precise tolerance removes any risk of control board short-circuiting, prevents contact sticking, and eliminates the heavy modifications often required when resorting to generic aftermarket relays.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eKey Features and Function:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePrecision Airflow Management\u003c\/strong\u003e: Reliable SPNO\/SPNC switching handles fan motors and auxiliary system loads securely.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eGenuine OEM Reliability\u003c\/strong\u003e: Factory-engineered with durable silver cadmium oxide contacts and a heavy-duty phenolic enclosure to meet strict Trane standards.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSafety Integration\u003c\/strong\u003e: Enclosed design protects internal relay components from moisture and dust, lowering the risk of electrical arcs or fire hazards.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePlug-and-Play Setup\u003c\/strong\u003e: Features convenient 1\/4\" quick-connect terminals for fast field wiring and is suitable for bracket, panel, or universal mounting.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eProduct Details and Key Specifications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e: RLY01720\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e: Trane \/ American Standard (Genuine OEM)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePart Type\u003c\/strong\u003e: Fan \/ General Purpose Power Relay\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCoil Voltage\u003c\/strong\u003e: 208\/240 V\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eContact Configuration\u003c\/strong\u003e: SPST (1 Form A \/ 1 Form B) — effectively functions as an enclosed SPNO\/SPNC setup\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 7-8A Inductive (Up to 25A Resistive depending on switching voltage)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePhase \/ Hertz\u003c\/strong\u003e: Single-phase (1PH) \/ 50\/60 Hz\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMounting\u003c\/strong\u003e: Bracket, Panel, or Universal\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eShipping Weight\u003c\/strong\u003e: ~0.3 lbs\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e🛠️ \u003cstrong\u003eHVAC Depot Pro Tip: Label Your Wires\u003c\/strong\u003e\n\u003c\/h2\u003e\n\u003cp\u003eWhen replacing a multi-terminal fan relay like the RLY01720, always turn off the high-voltage breaker to the air handler or furnace first. Before pulling any of the push-on quick connect spade terminals, use a permanent marker or electrical tape to label which wire goes to the normally open (NO), normally closed (NC), common (COM), and coil terminals. Reversing a line-voltage wire with a control circuit wire will cause an immediate short circuit and destroy your indoor control board or transformer.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eCross-Reference \u0026amp; Compatibility:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe RLY01720 is a direct OEM replacement for the following part numbers:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eOEM Numbers\u003c\/strong\u003e: RLY01720, White-Rodgers \/ RBM Equivalents\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eAftermarket\/Fasco\u003c\/strong\u003e: General-purpose enclosed switching relays from brands like Packard (e.g., PR384\/PR374) or White-Rodgers can serve as substitutes, provided the coil voltage and amperage limits align perfectly.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eExtensive Model Compatibility List:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eAir Handlers \u0026amp; Fan Coils\u003c\/strong\u003e: Fits thousands of high-voltage (208\/240V) Trane and American Standard indoor air handlers and fan coils utilizing a hardwired switching relay.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eVerify Specific Model\u003c\/strong\u003e: Consult your specific indoor equipment cabinet sticker or parts manual to verify compatibility with a 208\/240V SPNO\/SPNC fan relay.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Trane","offers":[{"title":"Default Title","offer_id":52237867549035,"sku":"RLY01720","price":35.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/RLY01720.jpg?v=1774989220","url":"https:\/\/tophvacparts.com\/products\/trane-rly01720-genuine-oem-replacement-relay-fan-spno-spnc-7-a-208-240-v-coil","provider":"HVAC Parts and Equipment Depot: Homeowners \u0026 Contractors Welcome | Plano, TX","version":"1.0","type":"link"}
