Industrial 36-557R3744 Capacitor

Rotom 36-557R3744 is an industrial round run capacitor for single‑phase motors, rated at 370/440 VAC with a dual capacitance of 55/7.5 MFD, a combination commonly used to provide the necessary phase shift for reliable motor operation in HVAC and general fan applications. The capacitor’s round form factor measures about 2.36 inches in diameter and 5.12 inches in length, matching the standard footprint for Rotom round capacitors used as OEM replacements. This part is typically employed in blower motors, fans, and other small‑ to medium‑sized single‑phase motors found in residential and light commercial heating, ventilation, and air‑handling equipment, where stable torque and consistent speed are important. The 36-557R3744 designation identifies the 55/7.5 MFD, 370/440 V variant, and it is widely stocked as a replacement part for compatible Rotom motor assemblies.
