Square D 750SV1F 0.75 Kva General Purpose Transformer

Product Description

The SQUARE D 750SV1F is a single-phase, general purpose transformer rated at 0.75 kVA. It accepts a 240 x 480 volt input and steps down to a 120/240 volt output, making it a standard choice for control circuit isolation and load-center voltage conversion in light commercial and industrial applications. The unit carries a NEMA 3R enclosure rating, allowing installation in both indoor and outdoor locations where exposure to rain and sleet is a concern. A 239 degrees F temperature rise rating indicates the thermal ceiling at full load. Licensed electricians and electrical contractors are the primary installers for this class of transformer.

The 750SV1F fits typical applications where single-phase step-down voltage conversion is needed for control circuits, small machine loads, or branch-circuit power conditioning. The dual-voltage primary (240 x 480 volts) gives installers flexibility to connect to either common single-phase service voltage. The 120/240 volt secondary supports split-phase loads and standard 120-volt control circuits. The NEMA 3R enclosure makes it suitable for rooftop mechanical rooms, outdoor equipment panels, and covered utility areas.

Key Features

• NEMA 3R enclosure rated for indoor and outdoor installation
• 239 degrees F temperature rise rating at full load
• RoHS compliant construction

Compatibility

Designed as an OEM-style replacement and general-use single-phase step-down transformer for light commercial and industrial control circuit applications requiring 240 x 480 volt primary input and 120/240 volt output.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lockout/tagout the supply circuit before making any connections to the primary or secondary terminals. Verify the primary tap setting matches the available service voltage before energizing. The NEMA 3R enclosure requires proper conduit entry sealing when installed outdoors to maintain the enclosure rating.
