ABB 9T85B3873

The ABB 9T85B3873 transformer is a solid choice when you need reliable, energy-efficient performance. This GE Type QL transformer meets NEMA TP-1 efficiency standards and offers flexibility with either aluminum or copper windings. Designed with a UL-recognized 220°C insulation system, it ensures durability and safety under demanding conditions.

One of the standout features is its quiet operation—thanks to core and coil assemblies mounted on rubber isolation pads that help keep noise levels down.

The transformer comes housed in a NEMA 2 drip-proof enclosure as standard, with optional weathershield kits available to upgrade it to NEMA 3R for outdoor use.

Built tough to comply with seismic standards like IEEE-693-2005 and IBC-2006, it also includes practical elements such as copper ground straps and robust packaging that guards against shipping damage. Installation is made easier with accessible mounting flanges featuring slotted holes at the front and back. Each unit undergoes 100% factory testing to verify coil integrity, electrical parameters, and noise levels.

Distributed by BSP Automation, the ABB 9T85B3873 transformer comes with clear, detailed documentation and labeling, helping you get it up and running smoothly—no sweat.
