Trane TSJ090A4S0K1CMA Rooftop Cooling Unit 7.5 Ton 460V

Product Description

The TRANE TSJ090A4S0K1CMA is a commercial rooftop cooling unit rated at 7.5 tons and designed for three-phase electrical service at 460 volts. This unit delivers packaged cooling capacity for commercial buildings and is typically installed on rooftop curb mounts as part of a central air distribution system. It is sized for mid-range commercial loads and is wired for 460V 3-phase power, making it suited for light commercial and medium commercial structures. Installation and commissioning are performed by licensed HVAC technicians familiar with commercial rooftop equipment, refrigerant handling, and three-phase electrical systems.

The TSJ090A4S0K1CMA is applied in commercial cooling applications where a self-contained rooftop unit is the preferred mechanical system. Typical installations include retail spaces, office buildings, schools, and light industrial facilities requiring packaged cooling without a separate condenser or air handler. The three-phase 460V electrical configuration is standard for commercial buildings served by a step-down transformer or dedicated commercial utility service.

Compatibility

Designed as an OEM commercial rooftop cooling unit within the TRANE TSJ product series for 460V three-phase commercial applications. Consult TRANE installation documentation and curb adapter specifications before ordering to confirm compatibility with existing roof curbs and ductwork configurations.

Installation Notes

This unit must be installed by a licensed HVAC contractor holding applicable refrigerant handling certifications per EPA Section 608. Disconnect and lock out all electrical power at the three-phase service disconnect before any service work is performed. Rooftop curb alignment, duct connections, and electrical terminations must comply with local mechanical and electrical codes as well as TRANE installation guidelines. Do not energize the unit without verifying correct phase rotation on the three-phase supply.
