Fulham Workhorse WH3-277-C Ballast

This Fulham Workhorse electronic ballast operates on a 277V AC supply and drives one or two fluorescent lamps. It supports a wide range of bulb types including T5, T8, T12, BX and DBX formats with wattages from 12 W up to 100 W. The unit uses instant start technology and functions down to -22 degrees F.

Installers needing 277V instant-start operation

Contractors wiring commercial fixtures on 277V circuits will find the voltage match and broad lamp compatibility useful. Buyers who need dimming control should look at a different unit because this model provides no dimming function. Projects requiring programmed or rapid start methods are not served by this ballast.

Input voltage 277V AC

The single specification that decides fit is the 277V AC input rating. If the supply voltage at the fixture is not 277V AC, this ballast will not operate correctly. Confirm the site voltage before purchase.

Questions about this item

Which fluorescent lamps can I run on the Workhorse WH3-277-C ballast?

It supports BX, DBX, T10, T12, T12U, T5, T5-Circuline, T6 and T8 lamps from 12 W to 100 W, with one or two bulbs per unit.

Will the ballast start reliably in a cold garage at -22 °F?

Yes, the minimum starting temperature is rated at -22 °F, so it will strike in freezing conditions.

How do I confirm the ballast is operating correctly after wiring it to 277 V?

The lamps should light instantly with no flicker; if they fail to strike or flicker, check wiring and lamp compatibility.
