FAQs
Yes. The unit is a single-phase 60 Hz transformer with 240/480 V primary and 120/240 V secondary, rated at 7.5 kVA. It is UL Listed and designed for indoor-outdoor service with a NEMA 3R enclosure, making it well-suited for control panels in automation and machine control applications.
Plan for outdoor or mixed environments using the NEMA 3R enclosure; ensure proper mounting clearance and ventilation for heat dissipation. If corrosion resistance is critical, consider the optional Grade 304 stainless steel enclosure with NEMA 4X protection. Verify mounting within a suitable enclosure that accommodates the 7.5 kVA unit and its wiring.
The transformer uses a NEMA 3R enclosure suitable for indoor-outdoor environments. There is an option for Grade 304 stainless steel enclosure with NEMA 4X protection for extra corrosion resistance in wash-down or chemical exposure areas. This combination supports reliable operation in industrial settings such as warehouses and process facilities.
The transformer is UL Listed, meeting recognized safety standards for electrical equipment. The enclosure options (NEMA 3R and optional NEMA 4X stainless steel) provide environmental protection conformance. These certifications and ratings help with end-user compliance, insurance requirements, and procurement approvals in regulated industries.
Encapsulation and robust enclosure reduce leakage paths and maintenance needs, improving mean time between failures in automation panels. The 7.5 kVA rating supports reliable power for control circuits, potentially lowering downtime. UL Listing and durable enclosure enhance long-term reliability, contributing to favorable total cost of ownership in manufacturing environments.
