The unit uses an LCD display to indicate rotation direction clearly without requiring an internal battery — the tester draws power directly from the circuit under test. Licensed electricians and HVAC technicians rely on this tool when commissioning motors, drives, and three-phase equipment where incorrect phase rotation can cause reverse operation or equipment damage. It covers a wide operating temperature range of 32 to 104 degrees F, making it suitable for both indoor and field service environments.\u003c\/p\u003e\u003cp\u003eThe FLUKE-9040 is used wherever three-phase power is present: commercial HVAC installations, industrial motor controls, variable frequency drives, generators, and utility-fed distribution panels. It is particularly useful during initial commissioning of three-phase compressors, pumps, and air handlers, where confirming correct phase sequence before energizing equipment is a critical step. The wide voltage and frequency range makes it compatible with both 50 Hz and 60 Hz systems, including variable-frequency-drive outputs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOperates from 40 to 700 VAC — covers low-voltage three-phase up to medium distribution levels\u003c\/li\u003e\n\u003cli\u003eFrequency range of 15 to 400 Hz supports VFD output testing as well as standard 50 Hz and 60 Hz systems\u003c\/li\u003e\n\u003cli\u003eNo battery required — powered entirely by the circuit under test\u003c\/li\u003e\n\u003cli\u003eLCD display provides clear phase rotation indication\u003c\/li\u003e\n\u003cli\u003eSelf-retaining test probes and alligator clips included for hands-free connection during testing\u003c\/li\u003e\n\u003cli\u003eMeets EN 61010 and EN 61557-7 safety and performance standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on three-phase AC systems operating between 40 and 700 VAC at 15 to 400 Hz, including standard 50 Hz and 60 Hz power systems and variable frequency drive outputs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tester is installed and operated by licensed electricians or qualified HVAC technicians in accordance with NFPA 70 (NEC) and applicable local codes. Always verify that the circuit voltage falls within the rated range before connecting the test probes. De-energize and lock out the circuit before making or breaking any wiring connections at the load; connect the tester leads first, then re-energize only for the test. Do not use this tester on circuits exceeding 700 VAC.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Phases\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Range\u003c\/strong\u003e: 40 to 700 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Range\u003c\/strong\u003e: 15 to 400 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay Type\u003c\/strong\u003e: LCD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range\u003c\/strong\u003e: 32 to 104 degrees F (0 to 40 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery Required\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards Met\u003c\/strong\u003e: EN 61010, EN 61557-7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Alligator Clips, Self-Retaining Test Probes, User Manual\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.44 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FLUKE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FLUKE-9040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FLUKE","offers":[{"title":"Default Title","offer_id":51544460362034,"sku":"FLUKE-9040","price":564.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0693b6c09614df11126a4353d2c72b06.jpg?v=1785927102","url":"https:\/\/voomisupply.com\/products\/fluke-fluke-9040-phase-rotation-tester-3-phase","provider":"Voomi Supply","version":"1.0","type":"link"}
