Capacitor, Dual Run, 45/5 uF, 440 Volt VAC, Round

Lennox (Mars®) 89M80 Dual Run Capacitor – 45/5 MFD, 440V, Round The Lennox 89M80, manufactured by Mars®, is a dual-section motor run capacitor designed for use in HVAC systems with permanent split capacitor (PSC) motors. It provides continuous-duty operation for both the compressor and condenser fan motor, with a capacitance rating of 45/5 microfarads and a voltage rating of 440V AC. This round capacitor features a metallized polypropylene film dielectric and is housed in a sealed aluminum case with a pressure-sensitive interrupter for overpressure protection. Standard ¼" quick-connect terminals allow for straightforward field installation and service replacement. Technical Specifications: Model: 89M80 Capacitance: 45/5 MFD (μF) Voltage Rating: 440V AC Shape: Round Terminals: ¼" male quick-connect Frequency: 50/60 Hz Dielectric: Metallized polypropylene film Enclosure Material: Aluminum Safety Feature: Internal pressure interrupter Operating Temperature Range: -40°C to +70°C Certification: UL Recognized Application Overview: Designed for dual motor operation in air conditioning condensers and heat pump systems. Supports permanent split capacitor (PSC) motors by providing continuous capacitance to the compressor and fan circuits. Compatible with OEM equipment that specifies a 45/5 MFD, 440V dual capacitor in round form factor. Suitable for residential and light commercial HVAC applications. Installation Guidelines: Ensure power is disconnected and the capacitor is discharged before replacement. Confirm capacitance and voltage match system specifications. Use correct terminal labels (C, FAN, HERM) for wiring connections. Mount securely and ensure exposure to vibration or moisture is minimized. Installation should comply with local electrical and mechanical codes. The Lennox 89M80 provides reliable power delivery to support motor efficiency and system performance in HVAC units requiring dual-run capacitors. It is designed to meet standard HVAC service requirements for consistent, high-duty operation.
