Product Description

The TX-BB-416Y-443Y.256-13A is a 9.6 kVA three-phase buck-boost transformer that bucks a 416V supply to 443V — a 6% voltage correction — bringing 443V-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 12.5A at 443V (9.6 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. Supplied as a two-unit open-delta bank for three-phase delta service.
