Philips Advance T8 Fluorescent Ballast - 347V AC | Instant Start

Philips Advance T8 Fluorescent Ballast (GOPA-4P32-SC-35M (197970)). When servicing a socketed fluorescent fixture, compare this model against the lamp schedule and supply before ordering. The 4 X F32T8 operating configuration distinguishes this ballast from versions intended for a different lamp count. This is the instant start version, so the fixture wiring and lampholder arrangement must suit that starting method. When comparing replacements, note the 0.88 ballast factor as well as the lamp and supply ratings.

Plan the electrical connection around this model’s 347V AC rating. The listed body dimensions are length 9.50 in., width 1.70 in., height 1.18 in.; use them when checking the available space around the ballast compartment. Follow the wiring diagram for this model when making the replacement connections.

Buying tip: Match the lamp designation, number of lamps and supply voltage to the existing ballast.
