Trane WSJ300A4S0R0ZRR Packaged Heat Pump 25 Ton 460V

Product Description

The TRANE WSJ300A4S0R0ZRR is a commercial packaged heat pump unit engineered for large-scale simultaneous heating and cooling demand. Part of the WSJ series, this unit delivers 300,000 BTU/h (25 tons) of capacity operating on a 460-volt, 3-phase power supply. The convertible airflow configuration allows the unit to be adapted for different discharge orientations during installation, adding flexibility for rooftop or ground-level mechanical applications. Licensed commercial HVAC technicians and mechanical contractors handle installation and commissioning of this class of equipment.

This unit is intended for commercial and light-industrial applications where high-capacity, packaged heating and cooling is required from a single rooftop or ground-mount chassis. The 25-ton output makes it well-suited for large retail spaces, warehouses, light manufacturing facilities, and similar structures that require a self-contained, all-electric heat pump solution. The 460-volt, 3-phase electrical requirement is standard for commercial building power distribution in this capacity range.

Key Features

• 300,000 BTU/h (25 ton) heating and cooling capacity in a single packaged chassis
• 460-volt, 3-phase power supply for commercial electrical infrastructure
• Convertible airflow design supports multiple discharge configurations for installation flexibility
• All-electric heat pump operation eliminates on-site combustion for heating
• WSJ series commercial platform built for large-scale mechanical system integration

Compatibility

Designed as an OEM commercial packaged heat pump unit within the TRANE WSJ series product family, intended for large-capacity commercial HVAC applications requiring 460-volt, 3-phase power.

Installation Notes

Installation must be performed by a licensed commercial HVAC contractor familiar with large packaged rooftop or ground-mount equipment. Disconnect and lock out all electrical power at the 3-phase disconnect before any service work. Verify that the building electrical service meets the 460-volt, 3-phase supply requirements and that all wiring complies with applicable NEC standards and local mechanical codes. Convertible airflow orientation should be confirmed against duct layout before the unit is set and secured.
