FAQs
For Class 1 Division 2 installations, plan for proper clearances around the unit, secure mounting on a rigid base compatible with the 244H frame, and ensure the enclosure is protected from direct impacts. Verify ambient conditions stay within enclosure ratings and follow Eaton installation guidelines to maintain UL Listed status.
The two taps at -5% FCBN allow voltage adjustment to compensate for line drop or transformer coordination with downstream loads. Use the taps when feeder distances or supply fluctuations cause under-voltage at secondary equipment; this helps maintain voltage within tolerance and reduces motor stalling and overheating.
Yes. The Z48G47T45 provides a 480 V primary and a 480Y/277 V secondary in a 3-phase arrangement, designed for hazardous locations. Its EPTZ design and UL Listed certification, along with Class 1 Division 2 compliance, make it appropriate for powering lighting, controls, and small motors in those environments.
This transformer is UL Listed and designed for Class 1 Division 2 hazardous locations (Groups C and D).
