Encapsulated EPTZ construction provides superior moisture resistance and fault isolation, boosting reliability in harsh environments. This design translates into fewer on-site failures and lower maintenance costs for critical power equipment. Ideal for chemical plants, refineries, and mining operations, the transformer protects sensitive equipment while meeting stringent safety codes. Copper windings and a 75 kVA rating deliver efficient, low-loss operation and robust heat management under peak loads. This translates to lower energy waste, cooler operation, and extended transformer life—critical for continuous manufacturing lines and sensitive automation systems. Indoor-Outdoor reliability: the NEMA 3R enclosure supports installation in varied environments without extra housing. The 66A wiring connection simplifies integration with existing switchgear and feeders, accelerating installation and reducing field rework. Voltage regulation via two -5% FCBN taps enables fine-tuning to maintain secondary voltage within tight tolerances under load changes, reducing equipment mismatch and nuisance trips. Comprehensive support and certification: UL Listed, Class 1 Division 2, Groups C and D, and a robust warranty provide confidence in safety, compliance, and long-term reliability, helping lower total cost of ownership.
