Ultrasave T5 Fluorescent Ballast - 277-347V AC | Programmed Start - ER254347MHT

ER254347MHT is the Ultrasave T5 Fluorescent Ballast. For maintenance of a fluorescent troffer or strip, this model must match the fixture’s supported lamp configuration. The 2 X F54T5HO operating configuration distinguishes this ballast from versions intended for a different lamp count. This is the programmed start version, so the fixture wiring and lampholder arrangement must suit that starting method. When comparing replacements, note the 1 ballast factor as well as the lamp and supply ratings.

This version is specified for 347V AC; that rating is part of the selection when replacing an existing fitting. The listed body dimensions are length 12.83 in., width 1.32 in., height 1.13 in.; use them when checking the available space around the ballast compartment. Follow the wiring diagram for this model when making the replacement connections.
