Eaton Specification Sheet - N38M37T75EE
KT-Factor nonlinear ventilated design provides improved thermal management and fault tolerance, reducing insulation stress and extending service life in varying load conditions. This translates to lower maintenance costs and higher uptime for critical production lines and automation stations. The optional voltage taps, 2 at +2.5% and 4 at -2.5%, enable precise secondary voltage control, maintaining equipment performance and reducing nuisance tripping in systems with fluctuating supply. UL Listing and NEMA TP-1 efficiency certification give assurance of compliance and reduced energy losses, supporting regulatory adherence and long-term operating cost savings. Aluminum coil construction paired with a 916A frame minimizes stray losses and supports reliable field service, while the WS19 weathershield option expands outdoor installation capability without compromising protection. The 75 kVA rating paired with 60 Hz operation aligns with common industrial feeders and distribution panels, enabling straightforward retrofits and scalable deployments in power management strategies.
