FAQs
This transformer is designed for hazardous Class 1 Division 2 environments with EPZ construction and a NEMA 3R enclosure. Plan for indoor-outdoor mounting, ensure adequate clearance and cooling, and use the 524H wiring connection for field installations. The unit weighs 131 lb, fits a 177H frame, and benefits from stainless enclosure compatibility in harsh sites.
It is rated for Class 1 Division 2 Groups C and D, with aluminum windings and a 5 kVA rating. The 480 V primary and 120/240 V secondary provide reliable isolation and step-down for controls. With UL Listed certification and a 115°C temperature rise, it maintains performance under elevated ambient conditions common in hazardous settings.
Yes. The Z48N11S05SS features an indoor-outdoor Weathershield design and a Grade 304 stainless steel enclosure noted in catalog data, supporting both indoor panels and outdoor installations. Its NEMA 3R enclosure enhances protection from rain and dust, while the EPZ configuration keeps critical components sealed and accessible for service.
The primary certification is UL Listed, indicating compliance with recognized safety standards. It is rated for Class 1 Division 2 hazardous locations (Groups C and D) with an EPZ design, and it employs a corrosion-resistant enclosure suitable for challenging environments, providing assurance for regulatory and safety requirements in industrial facilities.
With a rugged encapsulated design, aluminum windings, and a stainless enclosure, maintenance is typically minimal for routine inspections. The 5 kVA rating and 480 V to 120/240 V output support durable, reliable power for control panels, reducing downtime and replacement costs. A one-year warranty (or 18 months from shipment) adds financial protection during early operation.
