Trane WSJ300A4S0017Q0 Rooftop Heat Pump 25 Ton 460V

Product Description

The TRANE WSJ300A4S0017Q0 is a commercial packaged rooftop heat pump designed for large-scale heating and cooling applications. Rated at 25 tons nominal capacity and wired for 460V 3-phase power, this unit is built for rooftop installation on mid-to-large commercial structures. The self-contained packaged design consolidates the refrigerant circuit, air handler, and controls into a single cabinet, reducing installation complexity. Licensed commercial HVAC technicians and mechanical contractors are the primary installers for a unit of this class and capacity.

This unit is suited for commercial rooftop applications including office buildings, retail centers, warehouses, and light industrial facilities requiring centralized packaged HVAC. The 460V 3-phase electrical requirement makes it appropriate for commercial occupancies with established three-phase service. As a heat pump configuration, it delivers both cooling and heating from a single rooftop cabinet, eliminating the need for a separate gas heating section in qualifying climates and applications.

Key Features

• 25-ton nominal capacity for large commercial cooling and heating loads
• Heat pump configuration provides both heating and cooling from one packaged unit
• 460V 3-phase power input suited to commercial electrical service

Disconnect and lock out all electrical power at the main disconnect before any service or installation work. The unit requires a properly rated structural rooftop curb and must be rigged and set by qualified personnel using appropriate lifting equipment.
