Trane WSC120H4R0B005D Commercial Heat Pump 10 Ton 460V

Product Description

The TRANE WSC120H4R0B005D is a 10-ton, two-stage packaged heat pump designed for rooftop installation in light commercial and commercial buildings. Operating on 460 volts, three-phase power, this unit provides both heating and cooling from a single rooftop-mounted cabinet. Two-stage operation allows the system to run at reduced capacity during moderate load conditions, improving efficiency and reducing compressor cycling. Licensed HVAC technicians and commercial refrigeration mechanics are the typical installers for this class of equipment.

This unit is intended for light commercial and commercial rooftop applications where a self-contained heating and cooling solution is required. Typical install scenarios include low-slope or flat rooftops on retail, office, or warehouse buildings. The 10-ton capacity and three-phase electrical configuration make it suitable for medium-sized commercial spaces. The packaged design consolidates all refrigerant, heating, and air-handling components into a single cabinet, simplifying installation and service access on the roof deck.

Key Features

• 10-ton cooling and heating capacity in a single packaged rooftop cabinet
• Two-stage operation for improved part-load efficiency and reduced compressor wear
• 460V three-phase electrical supply matches standard commercial power infrastructure
• Packaged design eliminates the need for separate indoor and outdoor units
• Heat pump configuration provides both heating and cooling from one system

Compatibility

Designed as an OEM packaged rooftop heat pump replacement or new installation unit for commercial rooftop curb applications rated for 10-ton, 460V three-phase systems.

Installation Notes

Installation must be performed by a licensed HVAC contractor familiar with commercial rooftop equipment and applicable mechanical codes. Disconnect and lock out all electrical power at the distribution panel before servicing or making electrical connections. The rooftop curb must be properly flashed and sealed per local building code requirements. Refrigerant handling requires EPA Section 608 certification.
