Product Description

The TX-BB-252V-240V-31A is a kVA single-phase buck-boost transformer that bucks a 252V supply to 240V — a 5% voltage correction — bringing 240V-rated equipment back into its proper operating range. Wired as an encapsulated buck transformer (autotransformer), it carries only the correction portion of the load, so this unit corrects a much larger connected load: up to 30.63A at 240V ( kVA usable line capacity).

Resin-encapsulated in a NEMA 3R steel enclosure (ANSI 70 light grey) for indoor or outdoor mounting at the disconnect. Lead wires and terminal lugs, aluminum windings, 180°C insulation system, 115°C rise, 50/60 Hz, cETLus listed. Use two units in open-delta for three-phase delta systems, three for wye. In-stock units ship the same business day.
