FAQs
Install on a flat, solid mounting surface using the 912B frame footprint. Allow adequate ventilation for the 150 C rise rating and ensure WS38 weather protection if installed in exposure zones. Connect the primary to 480 V and secondary to 208Y/120 V circuits, following the enclosure manufacturer’s clearance and conduit guidelines.
It uses a K-Factor nonlinear design with aluminum windings and an electrostatic shield to manage harmonic currents and reduce heat buildup. This lowers overheating risk, helps maintain voltage stability, and supports reliable operation of drives and rectifier-fed equipment under non-linear loading.
Rated at 9 kVA, it is a three-phase transformer operating at 60 Hz with a 480 V primary and 208Y/120 V secondary. The two taps at -5% FCBN allow voltage adjustment to stabilize output under varying load; this improves regulation and reduces nuisance trips in automation systems.
Yes, the unit is UL Listed, confirming compliance with recognized safety standards for electrical equipment intended for industrial installations. This reduces procurement risk and supports compliance in facilities that require certified electrical components.
Eaton provides a warranty per policy 25-000: one year from installation or 18 months from shipment, whichever occurs first. For maintenance, ensure ventilation is unobstructed, inspect the electrostatic shield and windings periodically, and verify WS38 weather shield integrity in outdoor installations.
