FAQs
Installations must comply with hazardous location requirements and enclosure standards. The Z20N11E15CU uses a NEMA 3R enclosure and UL Listed certification for Class I, Division 2 service, providing protected operation in exposed environments. Plan for adequate clearance around the 13.38 in L x 15.52 in H x 13.2 in W footprint, proper input/output wiring, and routine access for maintenance.
The transformer supports primary voltages of 120/208/240/277 V and a 120/240 V secondary, with a 50/60 Hz frequency rating. This versatility enables compatibility with diverse site mains and enables efficient step-down for control panels and instrumentation without additional transformers.
Yes. The unit is designed for indoor-outdoor use with a NEMA 3R enclosure and a weather-resilient, shielded construction. UL Listed for hazardous locations (Class I Division 2) further supports safe operation in outdoor environments adjacent to process equipment and external switchgear.
Key certifications include UL Listed for hazardous locations, Class I Division 2 compliance (Groups A–D), and NEMA 3R enclosure rating. These align with industry safety standards for hazardous environments and help streamline regulatory documentation and site approvals.
With copper windings, robust encapsulation, and a rugged enclosure, this transformer offers low maintenance and high reliability in tough environments. Its fixed 15 kVA rating, absence of taps, and solid enclosure reduce ongoing adjustments and spare-part needs, contributing to predictable lifecycle costs and reduced downtime for critical electrical infrastructure.
