FAQs
For proper installation, ensure a stable pad or mounting frame compatible with the 918A frame. Verify adequate clearance for cooling and access to taps (+2.5% / -2.5%). Confirm 60 Hz electrical supply, 480 V primary, and 416Y/240 V secondary wiring, with copper windings and electrostatic shielding. Follow UL-listed installation guidelines and maintain the WS34 weather shield for outdoor or harsh environments.
The transformer provides taps at +2.5% and -2.5% to compensate for supply variations and maintain stable secondary voltage for sensitive equipment. This reduces voltage fluctuation-related downtime and prolongs equipment life, especially in facilities with variable incoming power or long feeder runs.
Yes. It is UL Listed and NEMA TP-1 compliant, with catalog notes indicating NEMA TP-1 efficiency. The design aligns with industry-standard safety and efficiency expectations for commercial and industrial power distribution, helping facilities meet regulatory requirements and optimize operating costs.
Key factors include the 225 kVA three-phase rating, copper windings for lower losses, and a regulated voltage profile with taps for stability. The unit’s 115°C rise supports demanding loads, while electrostatic shielding and the WS34 weather shield extend reliability in challenging environments typical of data centers and manufacturing floors.
The product carries Eaton’s warranty policy of one year from installation or eighteen months from shipment, whichever occurs first. This, combined with UL Listing, NEMA TP-1 compliance, and Eaton support tools, provides a predictable total cost of ownership and access to established technical resources and parts.
