ABB QL/QF Series Low-Voltage Dry-Type Transformer, UL Listed

The ABB QL/QF Series Low-Voltage Dry-Type Transformer is a UL Listed general purpose transformer engineered for over 20 years of reliable service in commercial and industrial power distribution systems. Representative configurations include 150 KVA capacity, 3-phase operation, 480V primary to 208Y/120V secondary voltage, and 60Hz frequency, with a 40°C temperature rise class among the three ratings offered across the line. Built to meet DOE 2016 efficiency standards and UL Energy Verified as energy efficient, the QL/QF family is available with aluminum or copper windings to match project and budget requirements.

Key Features

  • KVA Rating: Representative 150 KVA capacity for demanding low-voltage distribution loads, with additional capacities offered across the QL/QF line.
  • Phase Configuration: 3-phase design for balanced commercial and industrial power delivery.
  • Primary Voltage: 480V primary input for standard industrial service entrances.
  • Secondary Voltage: 208Y/120V secondary output supporting mixed lighting and power loads.
  • Temperature Rating: 40°C rise class, with all three temperature rise ratings available across the QL & QF line.
  • Frequency Rating: 60Hz operation for standard North American electrical systems.
  • Durable Construction: Core and coil assemblies mounted on rubber isolation pads to reduce operating noise.
  • Serviceable Design: Single-piece front/back panel is easily removable for simplified installation and maintenance.
  • Winding Options: Available with aluminum or copper windings to suit application and cost requirements.

ABB 9T10A1003 – Frequently Asked Questions

1) Will an ABB QL/QF dry-type transformer step 480V down to 208Y/120V for a lighting and receptacle panel?
Yes. The representative configuration of the ABB QL/QF Series is 3-phase, 480V primary to 208Y/120V secondary at 60Hz, which is the usual arrangement for feeding a panelboard carrying mixed 120V receptacle and lighting loads off a 480V service. The wye secondary gives you both 208V line-to-line and 120V line-to-neutral from the same panel.
2) Does the ABB QL/QF transformer meet DOE 2016 efficiency requirements for a new commercial build?
It does. The QL/QF family is built to DOE 2016 efficiency standards and is UL Energy Verified as energy efficient, so it satisfies the federal efficiency requirement that applies to general purpose low-voltage dry-type transformers on new construction and retrofit work. It is also UL Listed.
3) Is this ABB transformer seismically qualified for a project in California?
Yes. The QL/QF dry-type transformers are qualified to the seismic requirements of IEEE-693-2005 and to IBC-2021 and CBC 2022. CBC is the California amendment of the IBC, so it covers California jurisdictions, and IBC-2021 covers most other adopting states. Anchorage and mounting details still have to follow the engineer's seismic attachment drawings.
4) Should I specify aluminum or copper windings on an ABB QL/QF transformer?
Both are offered across the QL/QF line, and the choice is a project and budget decision rather than a performance one at the same kVA and efficiency rating. Copper windings are commonly specified where the engineer's spec calls them out or where a smaller physical footprint per kVA matters; aluminum is the more common general-purpose choice. Confirm which the drawing specifies before you order, because the two are not interchangeable model numbers.
5) What kVA sizes does the ABB QL/QF transformer line come in?
The QL/QF line is ordered by model number against kVA capacity, with six models offered running from 9T10A1001 through 9T10A1006. Model 9T10A1005 is the 112.5 kVA unit, and 150 kVA is among the capacities offered across the line. Order by the model number that matches the kVA on your one-line diagram.
6) What is the temperature rise rating on an ABB QL/QF transformer?
A 40 degree C rise class is the representative rating, and all three standard temperature rise ratings are offered across the QL and QF line. Rise class matters because a lower rise unit runs cooler at full load and gives you more overload headroom, while the engineer's spec will often name the rise it requires alongside the kVA.
7) Is the ABB QL/QF transformer quiet enough to mount in an occupied electrical room?
The core and coil assembly sits on rubber isolation pads to cut structure-borne noise from the unit, which is the main reason a dry-type transformer telegraphs hum into a building. That addresses transmission through the enclosure; wall or floor mounting still benefits from following the installation detail for isolated anchorage.
8) How hard is it to get into an ABB QL/QF transformer to land conductors or service it?
Access is straightforward: the front and back panel is a single piece that lifts off, so you are not chasing a dozen fasteners and multiple covers to reach the terminals for pulling conductors, checking taps, or torquing connections during maintenance.
