Ceiling heater for 277 VAC systems

The Dayton 54UD17 is an electric convection heater designed for surface or recessed ceiling mounting. It operates on a 277 VAC single-phase supply at 60 Hz and carries UL and CUL safety listings. This unit suits commercial or residential installations requiring overhead heat at this specific voltage.

375 watt output and 1280 BtuH capacity

The heater draws 1.4 amps to deliver 375 watts (0.375 kW) of warmth, producing 1280 BtuH. This output handles modest spot-heating tasks such as entryways, bathrooms or small offices. Larger areas or spaces with high heat loss will exceed the capacity of this single unit.

24 by 24 inch low-profile housing

The white powder-coated steel cabinet measures 24 inches square and only 1 inch high, allowing it to sit nearly flush with the ceiling. Lead wires are housed in flexible metal conduit with a J-box connector for code-compliant wiring. Buyers needing a deeper recess depth or a different voltage must select another model.

Questions about this item

Will the 277 VAC Dayton 54UD17 share a circuit with my existing 277 V heaters?

The heater draws 1.4 amps at 277 VAC, so it can share a 277 V circuit if the total load stays within the breaker rating.

How do I verify the 375 watt unit is heating correctly after mounting?

Measure the supply voltage at the J-box connector; it should read 277 VAC and the element should draw 1.4 amps when powered.

Does the 24 by 24 inch Dayton 54UD17 include a thermostat or only the lead wires in flexible metal conduit?

The box contains the heater with grounded lead wires in flexible metal conduit and a J-box connector; a thermostat is not included.
