Rated for 20 amps at 125 VAC and 10 amps at 250\/277 VAC, this SPDT\/SPST switch handles resistive, inductive, and motor loads up to 2 HP at 250 VAC. The 15-minute time cycle is set by a twist knob with no additional adjustments required. No neutral wire is needed, making it a practical choice for retrofit installations in existing switch boxes. Licensed electricians and HVAC technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThe C515M is suited for commercial and residential applications where timed shutoff of ventilating fans, HVAC equipment, whirlpool motors, self-storage lighting, and general motor and pump loads is required. The wall-mount form factor fits a standard in-wall electrical box. The brushed aluminum finish is consistent with commercial-grade switch trim. Operating temperature range of 32 to 122 degrees F covers typical indoor mechanical and utility spaces. The absence of a hold feature keeps operation straightforward for facilities where constant-on override is not needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e15-minute spring-wound time cycle with variable twist-knob setting\u003c\/li\u003e\n  \u003cli\u003eSPDT and SPST switching — no neutral wire required, retrofit-friendly\u003c\/li\u003e\n  \u003cli\u003e20 amp rating at 125 VAC for resistive and inductive loads\u003c\/li\u003e\n  \u003cli\u003eMotor load rating up to 1 HP at 125 VAC and 2 HP at 250 VAC\u003c\/li\u003e\n  \u003cli\u003eUL listed for both Canada and the US\u003c\/li\u003e\n  \u003cli\u003eMetal brushed aluminum finish for commercial wall-mount applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style commercial in-wall spring-wound timer suitable for ventilating fans, HVAC equipment, whirlpools, self-storage systems, motors, and pumps in standard wall-mount electrical enclosures.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NEC requirements. De-energize the circuit at the breaker and verify absence of voltage before wiring. No neutral conductor is required, simplifying connections in two-wire switch loops. Confirm the connected load does not exceed the contact current and horsepower ratings before energizing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Commercial\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTime Cycle\u003c\/strong\u003e: 15 minutes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Without Hold\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: SPDT, SPST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Current Rating\u003c\/strong\u003e: 20 amps at 125 VAC 50\/60 Hz (Resistive\/Inductive), 10 amps at 250\/277 VAC 50\/60 Hz (Resistive\/Inductive), 7 amps at 125 VAC 50\/60 Hz (Tungsten)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Power Rating\u003c\/strong\u003e: 1 HP at 125 VAC, 2 HP at 250 VAC (Motor)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Temperature\u003c\/strong\u003e: 32 to 122 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e: Wall\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\/Finish\u003c\/strong\u003e: Metal Brushed Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Ventilating Fans, HVAC, Whirlpools, Self Storage, Motors and Pumps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL (Canada and US)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.685 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.725 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.231 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: China\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NSI INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C515M\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NSI INDUSTRIES","offers":[{"title":"Default Title","offer_id":51284115783986,"sku":"C515M","price":69.62,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279383.jpg?v=1781068945","url":"https:\/\/voomisupply.com\/products\/nsi-industries-c515m-in-wall-spring-wound-timer-15-min","provider":"Voomi Supply","version":"1.0","type":"link"}
