Square D 1S67F General Purpose Transformer 1 Kva

Product Description

The SQUARE D 1S67F is a single-phase, general purpose transformer rated at 1 kVA. It is designed for step-up or step-down voltage conversion in commercial and light industrial electrical distribution applications. The unit carries a NEMA 3R enclosure rating, making it suitable for indoor or outdoor installations where protection from falling rain and sleet is required. Licensed electricians and electrical contractors typically install this transformer as part of a panel feed, control circuit, or branch distribution system. At 24.98 pounds, it is a compact unit appropriate for wall-mount or enclosure installation.

This transformer is suited for general purpose electrical distribution in residential, commercial, and light industrial settings. Typical applications include powering control circuits, lighting circuits, and step-down voltage conversion for HVAC controls, industrial equipment, and low-voltage systems. Its NEMA 3R rating makes it a practical choice for installations in mechanical rooms, utility areas, or exterior service panels where moisture exposure is a concern.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lockout the circuit at the upstream disconnect or breaker before any wiring work. Verify that primary and secondary voltage ratings match the circuit requirements before energizing. Ensure the mounting surface and enclosure are rated for the weight and environmental conditions of the installation site.
