Description
HPS, SK3A0225KK4S, K-Factor Transformer, Shielded, Series: Sentinel® K, 480 Delta VAC Primary, 480Y/277 VAC Secondary, 225 kVA Power, 60 Hz Frequency, 3 ph, Lug Connection, Floor Mounting, 220 deg C Insulation, NEMA 3R Enclosure, 86 to 104 deg F, 98.94 % Efficiency, Aluminum Winding, Steel Housing Material, 52 in H x 37-1/2 in W x 34 in D Dimensions
Features:
- Manufactured from quality non-aging, cold rolled and silicon steel laminations using state-of-the-art equipment
- Cores are precision cut to close tolerances which eliminates burrs and improves performance
- Core is coated to prevent the ingress of moisture and 150 deg C typical temperature rise
- Precision wound with copper or aluminum conductors that are electrically balanced to minimize axial forces during short-circuit conditions
- Robust interface between core and coils for better short circuit performance
- Standard type 3R enclosure
- Higher efficiency translates into increased profitability due to lower operating costs
- Decreased cost of ownership over the lifetime of the transformer
- Less air conditioning cost due to lower heat emissions
- Expanded catalog low voltage product up to 1000 kVA
- Standard 10 kV BIL rating on DOE 2016 low voltage distribution transformer products providing increased reliability and protection against critical equipment failure (including voltage spikes and other line transients)
- Standard integral floor and wall mounting brackets up to 45kVA allow for faster installation
- All units utilize a uniform 220 deg C insulation system with a 80 deg C, 115 deg C or 150 deg C temperature rise
- Industry leading design solutions, technology and materials continue the legacy of quality and reliability in all HPS products
- Expanded neutral bar for multiple customer connections
- Installer friendly outward facing enclosure mounting holes
- Factory installed grounding lug and vibration isolation pad
- 9 K-Factor and aluminum winding
- Offset outward facing floor installation holes for easy power tool access
- Typically 3.5% to 6.5% impedance
