Product Description
The TX-BB-240V-212V-53.07A is a 11.25 kVA single-phase buck-boost transformer that bucks a 240V supply to 212V — a 12% voltage correction — bringing 212V-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 53.07A at 212V (11.25 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.
