MARS 10874 5.5″ Azure Digi-Motor (1/8 – 1/3 HP, 208-230V, 825/1075 RPM) Inducer Motor

The MARS 10874 5.5″ Azure Digi-Motor (1/8 – 1/3 HP, 208-230V, 825/1075 RPM) Inducer Motor is a MARS inducer motor for HVAC repair and replacement work. Use it when the part number 10874 and the listed specifications match the equipment being serviced.

Azure is an electronically controlled motor (ECM) that replaces a multitude of applications. Azure motors are simple to install and Azure condenser fan motors connect the same as a standard PSC condenser fan motor, BUT WITHOUT the capacitor. Just plug the motor into a 115V power source (using supplied programming cable) and select 1 of 4 operating modes and then install the motor. Unlike other ECM motors, an outboard surge protector is included with the Azure wiring harness. This is a replaceable device that is much less expensive to replace than replacing the entire motor in the event of a power surge. Specifications: Multi horsepower
