Amrad RA2000 Motor Run Capacitor

Amrad RA2000 motor-run capacitor is a round, dual-value run capacitor for single-phase motors, delivering 37 µF and 44 µF in a single package. It is rated for 370–440 VAC and supports 50/60 Hz operation, aligning with typical North American HVAC systems. The RA2000/37-44 configuration is a common choice for replacing aging capacitors in outdoor condenser fans and blower motors, offering a compact form factor in a USA-made AmRad part that is widely stocked in service catalogs. Variants surface under related part numbers such as RA2000-44-305-256 and RA2000/37(456+505), reflecting different dual-capacitance combinations while preserving the same voltage and frequency range. Capacitance values are commonly specified with a tolerance around ±10%, which is consistent with many RA2000-series components. When replacing, verify the motor's nameplate capacitance and voltage rating to ensure the dual-capacitance arrangement (37 µF/44 µF) matches the original specification and to maintain proper motor performance.
