Trane WSC036H4R0A20CP Rooftop Heat Pump 3 Ton 460V

Product Description

The TRANE WSC036H4R0A20CP is a packaged rooftop heat pump rated at 3 tons nominal cooling and heating capacity. Operating on 460-volt, 3-phase power, this unit is built for commercial and light-commercial rooftop applications. It integrates refrigerant circuit components, air handling, and controls into a single self-contained cabinet, reducing the number of field connections required at installation. Commercial HVAC technicians and mechanical contractors install this unit on flat or low-slope rooftops, typically serving small to mid-size commercial spaces such as retail stores, offices, and light industrial facilities.

The WSC036H4R0A20CP is suited for commercial rooftop installations where a single-package configuration is required. The 460-volt, 3-phase electrical requirement makes it compatible with standard commercial electrical services. The Reliatel controls platform, referenced in the unit designation, supports DDC integration and building automation connectivity, which is common in commercial retrofit and new-construction projects where centralized controls are specified.

Key Features

• 3-ton nominal capacity packaged heat pump in a single rooftop cabinet
• 460-volt, 3-phase power supply for standard commercial electrical service
• Reliatel controls architecture supports DDC and building automation integration
• Self-contained design consolidates refrigerant, air handling, and controls on the roof
• Heat pump operation provides both heating and cooling from one unit

Compatibility

Designed as an OEM packaged rooftop heat pump replacement or new-installation unit for commercial light-commercial rooftop curb applications requiring 3-ton capacity and 460-volt 3-phase power.

Installation Notes

Installation must be performed by a licensed commercial HVAC technician or mechanical contractor familiar with rooftop equipment, refrigerant handling (EPA Section 608), and applicable local mechanical codes. Disconnect and lock out all electrical power before servicing or making any field wiring connections. Verify the structural capacity of the roof curb and confirm curb dimensions match the unit footprint before lifting the unit into place. Refrigerant line connections, if required for supplemental equipment, must comply with applicable codes and use properly rated materials.
