FAQs
This transformer uses a three-phase, 208V primary with 208Y/120V secondary and a 916A frame, designed for standard electrical rooms or enclosure spaces. Dimension details (approximately 28.22 in W x 23.42 in D x 48.56 in H) facilitate planning for mounting, clearance, and service access. Ensure proper ventilation, mounting hardware, and clearance per local codes.
Key specs include 75 kVA power rating, 60 Hz frequency, three-phase configuration, 208 V primary, 208Y/120 V secondary, and a 115°C maximum rise. It also features taps at +2.5% and -2.5% for voltage regulation, copper windings for efficiency, and electrostatic shielding for EMI control. UL Listed and NEMA TP-1 compliant ensures compliance and reliability.
Yes. The 75 kVA, 208V to 208Y/120V configuration, plus NEMA TP-1 efficiency and UL listing, makes it a strong match for automation cabinets and MCCs. Its copper windings and 115°C rise support reliable uptime under continuous duty, while the +/− taps help maintain stable voltages in dynamic production environments.
The unit is NEMA TP-1 compliant and UL Listed, with NEMA efficiency notes supporting energy performance. It includes electrostatic shielding to reduce EMI, and WS19 weather shield for outdoor or harsh indoor environments, ensuring safety and durability across industrial settings.
With copper windings and robust insulation (115°C rise), maintenance intervals are typically longer due to reduced heat stress. The 75 kVA rating provides capacity headroom, while warranty terms (Eaton’s policy) help manage risk. Regular inspections of connections, enclosure integrity, and ventilation are recommended to maximize lifespan and uptime.
