FAQs
For Class I Division 2 environments, install the Z48G22T30SS with a NEMA 3R enclosure to protect against moisture and dust. Plan mounting on a rigid, vibration-resistant base, accommodate the 610 lb weight, and ensure proper clearance for cooling and wiring access. The unit’s 25.15 in width, 26.58 in height, and 12.76 in depth should guide pad design and airflow clearance.
This is a 30 kVA, three-phase transformer with a 480 V primary and 240/120 V secondary. It operates at 60 Hz with aluminum windings and features two taps at -5% FCBN. The enclosure is rated for indoor-outdoor use (Weathershield), and the design supports a 150°C rise, making it suitable for demanding industrial environments.
Yes. Its Class I Division 2 designation, UL Listed certification, and rugged NEMA 3R enclosure make it appropriate for hazardous environments typical of chemical plants, refineries, and mining operations. The aluminum windings and robust enclosure provide durability and corrosion resistance in challenging sites while delivering reliable power to critical systems.
Key compliance indicators include UL Listed certification and NEMA 3R enclosure protection for indoor-outdoor installations. While not a CE or SIL specification, UL Listing and NEMA 3R rating are widely recognized and help meet industrial safety standards for hazardous-location transformers in many regions.
The transformer ships with a one-year warranty from installation or 18 months from shipment, whichever comes first, reducing lifecycle risk. Its durable enclosure (Grade 304 stainless steel) and rugged design limit corrosion and downtime, contributing to lower maintenance costs and improved uptime for critical processes in hazardous settings.
