30 kVA Three Phase Transformer 480V to 240/120V

This 30 kVA three-phase transformer efficiently converts a 480-volt delta input supply down to 240 volts delta, while also providing a 120-volt lighting tap for auxiliary power. It’s a versatile solution suitable for various industrial and commercial applications, especially in facilities with older electrical systems.

Designed as a ventilated dry-type unit with durable aluminum windings, it meets the stringent DOE 2016 efficiency standards. This transformer is also reverse-feed capable, meaning it can function as a step-up transformer if your application requirements change. The NEMA 1 enclosure is suitable for indoor use, with an optional weather shield available for outdoor installations.

Priced at $3,100, this transformer is built on a standard frame size (FR912B / FR940) and features a 150°C temperature rise with a 220°C insulation class. It’s an ideal choice for powering three-phase machinery at 240V and providing single-phase power for lighting and receptacles from the convenient 120V tap.
