Overview
The Advance 7C550P24 is a dry-film ballast capacitor engineered for use in HID (high-intensity discharge) lighting systems. This capacitor features 55MFD capacitance and 240VAC voltage rating, designed for high-pressure sodium lamps rated 150W with ANSI codes S55 and S56. The unit operates at 50/60Hz with a maximum case temperature of 105°C. This lot provides two capacitors in new, open-box condition—ideal for replacement or spare stock in lighting ballast applications.
