Square D 3-Phase 480V to 240/120V Transformer

Square D 3-Phase 480V to 240/120V Transformer

A Square D 3-Phase 480V to 240/120V Transformer is designed to step down 480-volt three-phase power to a 240-volt three-phase secondary with a 120-volt center tap. These transformers are commonly used for commercial, industrial, manufacturing, and electrical distribution applications where both 240V and 120V loads need to be supplied from a three-phase power system.

Electrical Supplies Unlimited carries and sources Square D transformers in a wide range of sizes and configurations, including new, used, surplus, discontinued, and hard-to-find transformers. If you need a Square D 480V to 240/120V transformer for a new installation, replacement project, maintenance application, or emergency repair, contact ESU at 858-558-2850.

Used Square D 480V to 240/120V Transformers

Used Square D 3-phase transformers can be an economical option when replacing an existing transformer or matching older electrical equipment. ESU buys and sells used transformers and can help identify equipment based on the manufacturer's nameplate, kVA rating, primary and secondary voltage, phase, enclosure, and other specifications.

Before installing a used transformer, the equipment should be inspected and evaluated by a qualified electrical professional. The nameplate information should also be carefully compared with the requirements of the electrical system.

Square D Transformer Replacement

Finding the correct replacement transformer requires more than matching the input and output voltage. The kVA rating, phase, frequency, winding configuration, taps, enclosure, temperature rise, physical dimensions, and installation requirements should all be considered.

If you are replacing an older Square D 480V transformer, ESU can help locate a current equivalent or identify a used, surplus, or discontinued transformer that matches the original application. Providing a photograph of the transformer nameplate can make identification much easier.

Obsolete and Hard-to-Find Square D Transformers

Older Square D transformers can become difficult to replace when an original model has been discontinued. ESU specializes in locating obsolete Square D transformers, discontinued transformers, used transformers, surplus transformers, and hard-to-find electrical equipment.

If you cannot find a replacement through normal electrical distribution channels, contact Electrical Supplies Unlimited. We may have the transformer in inventory or be able to locate one through our network of electrical equipment sources.
