Eaton N43M28T50XCU K-Factor nonlinear transformer -UL Listed
Part Number: N43M28T50XCU
Quick Summary
Eaton N43M28T50XCU is a K-Factor nonlinear ventilated transformer for 3-phase power distribution. In industrial facilities, harmonics, heat buildup, and space constraints can derail uptime. UL Listed safety certification helps meet critical compliance expectations, while the K-13 design and copper windings support reliable operation under non-linear loading. This unit combines a 50 kVA rating with a 416 V primary and 208Y/120 V secondary, enabling efficient step-down for plant feeders and equipment panels. The WS39 weather shield and robust frame 915D simplify installation in outdoor or harsh environments, reducing maintenance cycles. For procurement, you gain predictable performance, spare-part compatibility, and a clear path to long-term cost savings through efficient power management.
