Start Capacitor, 540-648MFD 125V

Vanguard Start Capacitor, 540-648MFD 125V

The BC-540 Vanguard Start Capacitor is a high-capacitance motor start capacitor designed to deliver the strong starting boost needed to get compatible single-phase motors up to speed quickly and reliably. Rated 540–648 µF at 110–125 VAC, it’s built with a round phenolic case and four 1/4" spade terminals for straightforward installation—because a motor that won’t start is just an expensive paperweight with attitude.
