Product Description

The CARRIER 40mbabq48xa3 is a 4-ton, multi-position ducted fan coil unit designed for ductless split heat pump systems using R-410A refrigerant. Rated at 48,000 BTU/h for both cooling and heating, it pairs with a compatible outdoor condensing unit to deliver single-stage heating and cooling in residential or light-commercial applications. The unit features an ECM blower motor rated at 235 watts and 780 RPM with four selectable speeds, producing airflow between 906 and 1,471 CFM depending on operating mode. ETL Listed for safety compliance. Licensed HVAC technicians handle installation and commissioning of this equipment.

This fan coil unit is suited for ducted multi-position installations where a high-capacity ductless heat pump system is required. It operates on single-phase, 208-230 VAC at 60 Hz and is compatible with R-410A refrigerant circuits. The unit supports sweat or braze connections on both the liquid line and suction line. Sound levels range from 43.4 to 53.8 dBA depending on blower speed and operating condition. Compatible equipment carries the Carrier, Bryant, and Payne product family designations within the 40MBAB product family.
