Trane WSC120H4R0B1KUA Packaged Rooftop Unit 10 Ton 460V

Product Description

The TRANE WSC120H4R0B1KUA is a commercial packaged rooftop unit (RTU) that integrates direct-expansion (DX) cooling with gas heat in a single self-contained cabinet. Rated at 10 tons of nominal cooling capacity, this unit operates on a 460-volt, three-phase power supply, making it suited for commercial electrical services. A licensed HVAC technician or mechanical contractor handles installation and startup. The WSC120H4R0B1KUA is designed for rooftop mounting and connects to existing ductwork for conditioned air distribution throughout the served space.

This unit is applied in light commercial and commercial settings where a single rooftop cabinet must handle both cooling and gas heating loads. Typical applications include retail spaces, office buildings, light industrial facilities, and similar structures requiring year-round climate control from a single rooftop-mounted system. The 10-ton capacity targets mid-size commercial zones. Installation requires coordination of electrical, gas, and ductwork rough-ins prior to setting the unit on the curb.

Key Features

• 10-ton nominal cooling capacity in a single packaged cabinet
• 460-volt, three-phase power supply for commercial electrical systems
• Integrated gas heat eliminates the need for a separate heating appliance
• Self-contained rooftop design simplifies mechanical room requirements
• DX cooling system for direct refrigerant-based cooling performance

Compatibility

Designed as an OEM commercial packaged rooftop unit for direct installation on standard commercial rooftop curbs with compatible ductwork connections. Consult Trane product documentation and the job specifications to confirm curb adapter, duct connection, and electrical service compatibility before ordering.

Installation Notes

Installation must be performed by a licensed HVAC contractor with applicable mechanical, electrical, and gas certifications. Disconnect and lock out all electrical power and shut off the gas supply before any service or installation work begins. The unit must be set on a properly sized and rated roof curb, and all ductwork, electrical, and gas connections must conform to local mechanical codes, NEC requirements, and IFGC standards. Do not energize the unit or open gas valves until all connections have been inspected and approved per local authority having jurisdiction requirements.
