The kit ships with the ballast, a 10 microfarad (MFD) dry film capacitor, a mounting bracket, and all required hardware. The circuit type is Constant Wattage Autotransformer (CWA) with a 5-tap configuration, supporting input voltages of 120, 208, 240, 277, and 480 volts at 60 Hz. It carries ANSI Code M57 and draws 219 watts of input power. The pre-wired igniter simplifies installation. Rated for cold-start operation down to -30 degrees C, this ballast kit suits demanding indoor and outdoor lighting applications. Licensed electricians handle replacement and new installation work.\u003c\/p\u003e\n\u003cp\u003eThis kit is applied in commercial and industrial HID lighting systems using 175W standard metal halide lamps. Typical installations include warehouse high-bay fixtures, parking structure lighting, retail canopy lighting, and outdoor area lighting where multi-tap voltage flexibility is required. The 5-tap design allows a single SKU to serve multiple service voltages on the same job site, reducing inventory requirements. The ANSI M57 rating defines lamp-ballast compatibility for standard 175W metal halide sources.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eComplete kit includes ballast, 10 MFD dry film capacitor, mounting bracket, and hardware\u003c\/li\u003e\n  \u003cli\u003e5-tap voltage configuration supports 120, 208, 240, 277, and 480 volts from a single unit\u003c\/li\u003e\n  \u003cli\u003eCore-and-coil Constant Wattage Autotransformer circuit for stable lamp operation\u003c\/li\u003e\n  \u003cli\u003ePre-wired igniter reduces field wiring time\u003c\/li\u003e\n  \u003cli\u003eCold-start rated to -30 degrees C for outdoor and unheated-space applications\u003c\/li\u003e\n  \u003cli\u003eUL Listed for Canada and the United States; RoHS compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 175-watt standard metal halide lamps meeting ANSI Code M57. The 5-tap input accommodates 120, 208, 240, 277, and 480-volt circuits, making it suitable as an OEM-style replacement or new-install ballast in commercial and industrial HID luminaires rated for 175W metal halide sources.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a qualified, licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lockout\/tagout the luminaire circuit completely before removing the existing ballast or connecting wiring to the new kit. Confirm the selected tap matches the supply voltage before making connections. Allow the lamp and ballast to cool fully before handling if servicing a fixture that was recently energized.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLamp Wattage\u003c\/strong\u003e: 175 W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Power\u003c\/strong\u003e: 219 W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLamp Type\u003c\/strong\u003e: Standard Metal Halide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: M57\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCircuit Type\u003c\/strong\u003e: Constant Wattage Autotransformer (CWA)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBallast Type\u003c\/strong\u003e: Core and Coil HID\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 120\/208\/240\/277\/480 volts (5-Tap)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacitor Rating\u003c\/strong\u003e: 10 microfarads (MFD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacitor Type\u003c\/strong\u003e: Dry Film\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIgniter Type\u003c\/strong\u003e: Pre-Wired\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Starting Temperature\u003c\/strong\u003e: -30 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKit Contents\u003c\/strong\u003e: Ballast, Capacitor, Mounting Bracket, Hardware\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 9.0 inches L x 7.0 inches W x 4.0 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL Listed (Canada and US)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoHS Compliant\u003c\/strong\u003e: Yes\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: KEYSTONE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MH-175A-P-KIT-3\/1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEYSTONE","offers":[{"title":"Default Title","offer_id":51284044775730,"sku":"MH-175A-P-KIT-3\/1","price":131.81,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279494.jpg?v=1781067069","url":"https:\/\/voomisupply.com\/products\/keystone-mh-175a-p-kit-3-1-175w-hid-ballast-kit-5-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
