Hammond C1F003LES 3 Kva Distribution Transformer

Product Description

The HAMMOND C1F003LES is a single-phase, copper-wound, encapsulated distribution transformer rated at 3 KVA. Designed for step-down distribution applications, it accepts a 240/480 volt dual-voltage primary and delivers a 120/240 volt secondary output suitable for powering standard single-phase loads. The fully potted encapsulation protects the windings against moisture, dust, and vibration, making this unit well suited for demanding industrial and commercial service environments. Licensed electricians and electrical contractors install this class of transformer as part of a branch distribution system or standalone power conversion installation.

This transformer is appropriate for light commercial and industrial facilities where a compact, encapsulated design is required. The dual-voltage primary allows flexibility when the available service voltage is either 240 or 480 volts, while the 120/240 volt secondary supports both standard outlet circuits and single-phase 240 volt equipment. Typical applications include machine tool feeds, control panel power supplies, and general-purpose step-down service in manufacturing or mechanical rooms.

Key Features

• 3 KVA capacity supports a range of single-phase branch distribution loads
• Dual-voltage primary (240/480 volts) provides installation flexibility across available service voltages
• 120/240 volt secondary supports standard outlet and 240 volt single-phase equipment simultaneously
• Copper windings provide reliable conductivity and thermal performance
• Fully encapsulated (potted) construction resists moisture, dust, and vibration

Compatibility

Designed as an OEM-style encapsulated distribution transformer for single-phase 240/480 volt primary to 120/240 volt secondary applications in commercial and industrial electrical systems.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 450 governing transformer installations. De-energize and lock out all upstream power sources before making any primary or secondary connections. Verify that the primary tap connections match the available service voltage before energizing. Ensure the transformer is mounted on a surface capable of supporting its weight and that adequate ventilation or clearance is maintained per manufacturer and code requirements.
