FAQs
For Class 1 Division 2 environments, mount the encapsulated transformer in a compliant, ventilated space with proper clearance for service access. Use the Grade 316 stainless steel enclosure and NEMA 3R rated housing to withstand indoor-outdoor conditions, and ensure wiring connections meet the 66A feeder requirements and local electrical codes.
The unit is a three-phase 75 kVA transformer with a 480 V primary and 208Y/120 V secondary. Taps are provided at -5% FCBN to accommodate input voltage variations, supporting stable load operation for motors, PLCs, and control panels without oversized systems or frequent venting.
Yes. The transformer is designed for hazardous locations (Class 1 Div 2, Groups C and D) with an EPTZ design, copper windings, and UL Listing, providing safer operation and easier regulatory compliance in chemical processing and similar facilities.
It is UL Listed and housed in a Grade 316 stainless steel enclosure with a NEMA 3R rating, optimized for indoor-outdoor use and corrosion resistance, essential for harsh industrial environments and cross-site deployments.
Expect low maintenance due to robust encapsulation and copper windings, with a warranty policy of 25-000 (one year from installation or 18 months from shipment). The design reduces downtime, improves reliability, and supports longer life in demanding facilities, delivering favorable total cost of ownership.
