Capacitor, Dual Run, 45/10 uF, 440 Volt VAC, Round

Lennox by Mars® 89M83 Dual Run Capacitor – 45/10 MFD, 440V AC, Round The Lennox 89M83 is a dual motor run capacitor engineered for HVAC systems utilizing permanent split capacitor (PSC) motors. With a capacitance rating of 45/10 microfarads (MFD) and a voltage rating of 440V AC, this round-style unit is designed to provide continuous-duty operation to both the compressor and condenser fan motor circuits. Manufactured with metallized polypropylene film dielectric and housed in a sealed aluminum case, the 89M83 includes a pressure-sensitive interrupter for safety against internal overpressure. It features standard ¼" male quick-connect terminals and is compliant with UL 810 safety standards. Technical Specifications: OEM Part Number: 89M83 Capacitance: 45/10 MFD (μF) Voltage Rating: 440V AC Configuration: Dual run Shape: Round Terminals: ¼" male quick-connect Dielectric Material: Metallized polypropylene film Case Material: Aluminum Protection: Internal pressure-sensitive interrupter Temperature Range: -40°C to +70°C Certification: UL 810 Application Notes: Designed for use in Lennox HVAC systems requiring a 45/10 MFD dual capacitor at 440V AC. Supports continuous-duty operation in PSC motor circuits powering both compressor and fan motors. Suitable for residential and light commercial applications where OEM replacement is required. Installation Guidelines: Ensure the system is de-energized and existing capacitor is fully discharged before removal. Match both microfarad and voltage ratings with original equipment specifications. Terminals are marked (C, FAN, HERM) to guide correct wiring. Mount the capacitor securely and protect from vibration and moisture. Installation should be performed in compliance with applicable local and national codes by a qualified technician. The 89M83 is built to original Lennox specifications and is intended for high-reliability dual-motor support in HVAC systems. Its construction and performance ratings make it a suitable choice for field replacements and system service in demanding environments.
