Appleton HS5F10AS 10 Kva Dry Type Transformer 480-120/240V

Product Description

The APPLETON HS5F10AS is a dry type distribution transformer rated at 10 KVA, designed for single-phase power distribution in industrial and commercial electrical systems. It steps down a 480-volt primary supply to a 120/240-volt secondary output, making it suitable for feeding lighting panels, receptacle circuits, and general-purpose loads. At 155 pounds and with a compact footprint, this unit is sized for wall-mount or floor-mount installation in electrical rooms, control rooms, and equipment enclosures. Licensed electricians and electrical contractors are the primary installers for this class of transformer.

This transformer is applied in industrial facilities, commercial buildings, and manufacturing environments where 480-volt distribution is present and 120/240-volt single-phase loads must be served. Typical applications include machine tool circuits, lighting branch panels, and control power feeds. Its dry type construction eliminates the need for liquid cooling or containment, making it well suited for indoor installations where oil-filled units are not permitted or practical.

Compatibility

Designed as an OEM-style single-phase dry type distribution transformer for 480-volt primary systems requiring 120/240-volt secondary output in commercial and industrial electrical installations.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NEC Article 450 governing transformer installation, clearances, and overcurrent protection requirements. Disconnect and lock out all power sources before handling or wiring the unit. At 155 pounds, mechanical lifting assistance or proper rigging should be used to position the transformer safely. Verify that secondary overcurrent protection and grounding are installed per applicable local codes before energizing.
