Square D 750SV46F Buck Boost Transformer 0.75 Kva

Product Description

The SQUARE D 750SV46F is a single-phase buck boost transformer rated at 0.75 kVA, designed to make small voltage corrections in electrical distribution systems. It accepts 120 x 240 volt input and delivers 16/32 volt output at 60 Hz, allowing electricians to raise or lower line voltage by a fixed increment rather than providing full isolation. The unit carries a NEMA 3R enclosure rating, meaning it is suitable for both indoor and outdoor installation in locations subject to falling rain. It is RoHS compliant and intended for use in commercial and light industrial electrical service work.

Buck boost transformers like the 750SV46F are commonly installed where supply voltage is slightly off from equipment requirements — for example, correcting a 208-volt service to 230 volts or trimming an elevated 240-volt feed. Typical applications include motor circuits, HVAC equipment feeds, lighting systems, and general electrical panel work where a full isolation transformer is not required. A licensed electrician performs this installation in accordance with NEC Article 450.

Key Features

• 0.75 kVA power rating handles small voltage-correction loads without oversizing
• 120 x 240 volt input with 16/32 volt output windings for flexible buck or boost configurations
• Single-phase, 60 Hz design suited to standard North American electrical service
• NEMA 3R enclosure rating approved for indoor and outdoor installation
• RoHS compliant construction

Compatibility

Designed as an OEM-style replacement or new-installation buck boost transformer for single-phase 60 Hz electrical distribution applications requiring NEMA 3R environmental protection.

Installation Notes

Installation must be performed by a licensed electrician in compliance with NEC Article 450 and any applicable local codes. De-energize the circuit completely and verify absence of voltage before making any connections. The NEMA 3R enclosure requires proper conduit entry sealing to maintain its outdoor-rated integrity. Do not exceed the 0.75 kVA nameplate rating when sizing connected loads.
