FAQs
Plan for the 23.42 in depth, 28.22 in width, and 48.56 in height footprint, with adequate clearance for ventilation and wiring. Use the 916A frame mounting and ensure proper access to the primary and secondary connections, including the taps (+2.5% FCAN, -2.5% FCBN) for voltage adjustment.
Verify 112.5 kVA rating, three-phase configuration, 480 V primary voltage, 480Y/277 V secondary voltage, 60 Hz frequency, and 150 °C rise. Confirm aluminum windings, electrostatic shield, and tap positions to match site voltage conditions and load requirements.
Yes. The product supports WS19 weather shielding and a ventilated design for enhanced cooling, making it suitable for outdoor installations or spaces with higher ambient temperatures while maintaining electrical performance.
It is UL Listed, indicating conformity with recognized electrical safety standards. This certification helps with site compliance, reduces procurement risk, and supports regulatory documentation during audits or inspections.
The K-Factor nonlinear ventilated design, EMI shielding, and robust thermal margin contribute to longer service life and reduced maintenance needs. Field voltage taps allow you to adapt to voltage drift without replacing equipment, delivering lower lifecycle costs.
