Rectorseal M10503 Condenser Fan Motor 1.5 Hp 1140 Rpm

Product Description

The RECTORSEAL M10503 is a three-phase induction condenser fan motor rated at 1.5 HP and 1140 RPM, built for continuous-duty commercial HVAC applications. It operates on 208-230/460 volt three-phase power, making it suitable for a wide range of commercial refrigeration and air conditioning condensing units. The motor features ball bearings for long service life under sustained load and an OPAO enclosure rated for outdoor air-over service. Reverse rotation is factory set to match standard condenser fan blade configurations. Automatic thermal protection provides a built-in safeguard against overheating during operation.

This motor is intended for commercial condenser fan applications where a robust, continuously rated three-phase motor is required. Typical installation scenarios include rooftop condensing units, remote condenser assemblies, and commercial refrigeration rack systems. The 208-230/460 volt dual-voltage configuration allows the motor to be wired for either low-voltage or high-voltage three-phase service, providing flexibility across different commercial electrical services. It is sized for replacement or new-installation use by licensed HVAC and refrigeration technicians working on commercial equipment.

Key Features

• 1.5 HP continuous-duty rating for sustained commercial operation
• Three-phase induction motor design for reliable, low-maintenance performance
• Ball bearing construction supports extended service life under constant airflow loads
• OPAO enclosure suited for outdoor air-over condenser fan service
• Factory-set reverse rotation for direct condenser fan blade compatibility
• Automatic thermal protection guards against overtemperature conditions

Compatibility

Designed as an OEM-style replacement three-phase condenser fan motor for commercial condensing units and refrigeration equipment requiring a 1.5 HP, 1140 RPM, 208-230/460 volt motor with reverse rotation.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician familiar with three-phase motor wiring and NEC requirements. Disconnect and lock out all electrical power to the condensing unit before removing the existing motor or handling any wiring. Verify the supply voltage and phase sequence match motor nameplate requirements before energizing. Confirm fan blade pitch and hub compatibility before final assembly to ensure proper airflow direction.
