Trane WHC074H4RKA5MG5 Heat Pump 6 Ton 460V 3ph

Product Description

The TRANE WHC074H4RKA5MG5 is a 6-ton commercial heat pump unit designed for heating and cooling applications in mid-size commercial or light industrial buildings. Operating at 460 volts, 3-phase power, this unit is built for installations where single-phase power is not available and higher electrical efficiency is required. Licensed HVAC technicians and commercial refrigeration mechanics are the primary installers. The 3-phase configuration supports the demands of larger compressor loads while the 6-ton capacity covers substantial conditioned square footage in a single unit.

This heat pump is suited for commercial rooftop, ground-level, or mechanical room installations where a packaged or split heating and cooling solution is required. The 460V 3-phase electrical requirement makes it appropriate for light commercial buildings, retail spaces, and small industrial facilities with proper electrical infrastructure already in place. Installation is typically performed as part of a new construction mechanical system or a direct replacement of an equivalent-capacity commercial heat pump unit.

Key Features

• 6-ton nominal cooling and heating capacity for mid-size commercial applications
• 460-volt, 3-phase power supply for reduced amperage draw and motor efficiency
• Heat pump configuration provides both heating and cooling from a single refrigerant-based system
• Commercial-grade construction suited for demanding installation environments

Compatibility

Designed as an OEM-style commercial heat pump replacement or new-installation unit rated at 6 tons and 460V 3-phase electrical supply. Consult TRANE engineering documentation and the unit nameplate to confirm mechanical, electrical, and refrigerant circuit compatibility before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician holding appropriate EPA Section 608 certification for refrigerant handling. Disconnect and lock out all electrical power at the service disconnect before beginning any mechanical or electrical work. Verify that the existing electrical infrastructure meets the 460V 3-phase supply requirements and that all wiring and overcurrent protection are sized per NEC guidelines. Do not commission the unit without confirming proper refrigerant charge, airflow, and electrical connections per the manufacturer installation instructions.
