Applications and common use cases 112.5 kVA
A 112.5 kVA transformer is widely used across commercial and infrastructure projects where moderate three-phase load capacity is required. It provides sufficient headroom to support the installation of distribution panels while maintaining efficient power delivery across the site.
This unit is a staple in commercial power distribution systems that utilize three-phase pad-mount transformers, especially where underground service and tamper-resistant equipment are required.
Because of its versatility, the 112.5 kVA rating often appears in projects where electrical engineers need reliable capacity without oversizing the electrical infrastructure.
Common applications include:
- Retail centers and commercial buildings
- Small manufacturing or fabrication facilities
- Municipal infrastructure and public buildings
- EV charging installations and distributed energy systems
- Edge data centers and AI inference infrastructure
- Multi-tenant commercial properties and office buildings
AI infrastructure and edge data applications 112.5 kVA
As AI workloads expand beyond hyperscale facilities, smaller edge data environments are becoming standard in commercial buildings, telecom sites, and regional infrastructure.
A 112.5 kVA transformer provides the necessary support for localized AI computing clusters, networking equipment, cooling systems, and dedicated electrical panels in these environments.
In these scenarios, reliable voltage regulation and consistent three-phase power are critical for protecting and powering sensitive computing hardware.
Typical AI-related deployments include:
- Edge AI inference nodes supporting low-latency applications
- Regional telecom infrastructure integrated with GPU compute hardware
- Industrial AI monitoring systems within manufacturing and fabrication plants
- Smart city infrastructure, including traffic systems and public safety networks
- Distributed micro data centers located near end users
Sizing and selection considerations 112.5 kVA
Choosing the right transformer capacity requires evaluating both current load demand and expected growth. A 112.5 kVA transformer is commonly selected for facilities with moderate three-phase loads or distributed electrical panels serving multiple circuits.
If your calculated demand approaches the upper limits of this capacity, you may want to compare adjacent sizes. For example, a 75 kVA pad-mount transformer may be appropriate for smaller installations, while a 150 kVA pad-mount transformer provides additional headroom for future expansion.
If you are still determining the correct size, you can also browse transformers by kVA rating to compare available capacities.
When evaluating this size, engineers typically consider:
- Connected Load: Total demand across panels and equipment
- Load Diversity: Analysis of expected peak demand versus average use
- Operational Loads: Power factor and motor startup requirements
- Scalability: Planned expansion of electrical infrastructure
Common voltage configurations 112.5 kVA
A 112.5 kVA transformer can be specified with various primary and secondary voltage combinations, depending on the facility's electrical distribution architecture.
Pad-mounted construction allows the transformer to be installed outdoors on a concrete pad, simplifying installation and improving safety in public-facing environments.
Typical configurations include:
- Primary Voltages: 4.16 kV, 7.2 kV, 12.47 kV, or 13.8 kV
- Secondary Voltages: 480Y/277 V, 208Y/120 V, or 240 V
- Phase Configuration: Three-phase
- Winding Design: Delta or grounded wye primary with wye secondary configurations for commercial distribution

What is a 112.5 kVA transformer used for?
A 112.5 kVA transformer is standard for commercial buildings, light industrial facilities, and municipal infrastructure requiring moderate three-phase power. Typical uses include powering distribution panels, HVAC systems, lighting circuits, and small localized data infrastructure.
What voltages are available for a 112.5 kVA transformer?
Common configurations include medium-voltage primaries such as 7.2 kV, 12.47 kV, or 13.8 kV, with secondary voltages like 480Y/277 V or 208Y/120 V. Exact voltage combinations are determined by utility service and facility distribution requirements.
Is a 112.5 kVA transformer suitable for commercial buildings?
Yes. This capacity is widely used in retail centers, office buildings, and small industrial facilities where moderate three-phase electrical loads must be distributed reliably and efficiently.
How do I know if a 112.5 kVA transformer is the right size?
Engineers determine the appropriate size by calculating total connected load, diversity factors, and future capacity requirements. If the expected load approaches this transformer’s rating, a larger unit may be recommended to provide a buffer for expansion.
What is the difference between pad-mount and dry-type transformers?
Pad-mount transformers are oil-filled, tamper-resistant outdoor units installed on concrete pads, commonly used for utility or commercial distribution. Dry-type transformers are generally installed indoors and rely on air cooling rather than liquid insulation.
What is the lead time for a 112.5 kVA transformer?
Lead times vary based on voltage configuration and inventory availability. While standard configurations may ship sooner, custom builds will require additional manufacturing time. Requesting a quote is the most accurate way to confirm a delivery timeline.
