FAQs
Consider mounting in a protected enclosure that meets the NEMA 3R rating for indoor-outdoor use. Provide proper clearance for ventilation, ensure the 3A wiring connection is secured, and verify primary and secondary voltages (240/480 V to 120/240 V) align with the control circuits. Follow manufacturer guidelines for wiring terminations and safety clearances.
The unit is a 1 kVA, 60 Hz, single-phase transformer with a primary voltage of 240/480 V and a secondary voltage of 120/240 V. It uses copper windings and has a temperature rise rating of 115 °C. The enclosure is NEMA 3R rated and designed for indoor-outdoor service.
Yes. Its general-purpose encapsulated design, UL Listing, and NEMA 3R enclosure make it well-suited for control panels and distributed power in manufacturing lines. The 1 kVA rating supports PLCs, relays, and auxiliary circuits, while copper windings offer efficient, low-heat operation in compact footprints.
It is UL Listed and housed in a NEMA 3R enclosure, providing reliable protection against dust and moisture in indoor-outdoor environments. Catalog notes also indicate a Grade 304 stainless steel enclosure option for enhanced corrosion resistance, which can be important for damp or washdown areas.
Encapsulated construction and weatherproof enclosure reduce exposure to moisture and contaminants, lowering corrosion risk and downtime. The 1 kVA, copper-wound design improves efficiency and heat management, contributing to longer service life, fewer maintenance cycles, and favorable total cost of ownership over competing, less rugged options.
