Brand: Halco · SKU: CAP/MH400/DRY · UPC: 807154558681 · Category: Lamps & ballasts · Type: Ignitors & Capacitors
The Halco CAP/MH400/DRY is a 24 microfarad, 400 volt dry-type capacitor listed under Halco's Ignitors and Capacitors subcategory for metal halide lighting applications. Like other MH-series capacitors in Halco's line, it is a service replacement component rather than a complete fixture, intended for electricians and maintenance contractors repairing an existing metal halide ballast circuit. The capacitor's role in a metal halide ballast is to correct power factor and assist the ballast and ignitor in starting and sustaining the lamp's arc. This part carries a dry-type construction, distinguishing it from Halco's oil-filled MH capacitors, and its 24 MFD, 400 volt rating needs to be matched to the original component's specification for the ballast circuit to function correctly after replacement. Contractors stocking parts for metal halide fixture service commonly keep a range of Halco MH capacitors on hand across different capacitance and voltage combinations, since ballast manufacturers use different values depending on fixture wattage, and this 24 MFD, 400 volt dry unit covers one of those common combinations.
The CAP/MH400/DRY is a dry-type capacitor rated 400V, while the CAP/MH1000 is an oil-filled unit rated 480V; both are 24 MFD.
